Back in January, we had a week-long internal "make-a-thon" where a bunch of people across the company got into teams, did some brainstorming, and worked to improve various parts of our UI. Bonus if they had something to do with moderator or power user tools. One of those teams took on the Tag Synonyms dashboard. It's not a page that sees a lot of traffic, all things considered, and so it hasn't received much attention of the years since its creation.

But wait, you say. January? It's June now. Well... as always, a bunch of things got in the way. Still, it's been my job over the last little while to take their work and get it the last little bit over the hump to the finish line.

The first phase of this is ready for deployment. We're going from this:

screenshot of the old UI

to this:

screenshot of the new UI

In a sense, this is largely a facelift, but we've put thought into a few UX bits here:

  • The "synonym" and "target" columns are reversed now, so the table can be read from left to right;
  • instead of sub-tabs, we have an actual sortable table;
  • actions available to moderators are cued by a button, not showing up out of nowhere on hover.

We also added a way to vote on the synonyms directly from the Pending Approval tab:

screenshot of the voting UI

All in all, there should be no functional regressions while the whole page fits better into our current site design. I'm still working on a few other things here (such as creating modal-based workflows for tag merging and synonym creation), but I wanted to ship this first set of changes because, well, I think it looks pretty damn neat and I'm stoked to get it out in front of folks. Plus there's some tech debt that needs to be paid down before the other features can be rolled out and delaying what's ready now for the sake of addressing it feels wrong.

What do y'all think? Feel free to post your feedback as an answer to this question.

Update: a modal-based tag merge workflow is live. Tag synonyms can now be merged with the target tag directly from the dashboard.

    I think this is mostly a case of re-arranging the deck chairs on the Titanic. The fundamental flaw of the tag-synonym system (the difficulty of getting permission to suggest or vote on synonyms) is still present, making this effectively a moderator-only page.

  • @Mark I agree that suggesting synonyms has a high bar (although less so on beta sites). The voting, however, only has a tag score requirement (answer scores in that tag need to add up to at least 5), which seems reasonable. We still have discoverability issues with this page in the first place, but hopefully having voting controls on it directly now will make it more useful to non-mods if they can find it in the first place.

    The reason most of us mere mortals don't bother with the tag synonyms page is that like @Mark said, we don't have the necessary permissions. Thus, the synonyms page is this huge practical joke, stringing you along thinking you can improve something... until at the last second it says "MWA HA HA HA HA! Just kidding! I won't let you do that because you're a puny weakling! MWA HA HA HA HA!" Until and unless that part is improved, it really is just rearranging deck chairs on the Titanic.

    Is there a reason not to give tag synonyms their own review queue? It seems like a much simpler solution to the discoverability problem. At The Workplace we have pending tag synonyms going back to 2014 because no one ever thinks to go there. If eligible voters got a notice in their queue whenever a new synonym was proposed, things wouldn't ever stay pending for very long.

but now available as a userscript on Stack Apps.

Please change the voting buttons. We're Stack Exchange, not Facebook ... One does not simply like or dislike a synonym proposal.

enter image description here

I understand positioning the score between two triangles (like on posts) might eat too much vertical space, but maybe you can position them horizontally like this: ^ 0 v. Or bring back the old synonym vote buttons, IMHO they were fine size-wise ... maybe that's not such a good idea for touchscreens.

    Hey, just because Facebook ruined "thumbs up" for everyone, doesn't mean it's a bad choice. ;) We thought about it and ended up going with different controls because on one hand, the arrows fit our existing UI pattern, but on the other... they look odd side by side, even with a score in-between.

Not sure whether it is a bug or known feature.

If I filtered a tag, in the result set I want to sorting the data, so sorting the result by clicking the sorting icon, but instead of sorting with in the result set, it cleared the filter text and reset the filtered result set.

I expect when the search result set is displaying, clicking on the sort icon should sort with in the result set.

I don't see a way to see all the proposed synonyms. The old one had 4 tabs:

  1. All
  2. Suggested
  3. Active
  4. Merge

The new one has just 3:

  1. Active (analogous to 3)
  2. Pending Approval (analogous to 2)
  3. Pending Merge (analogous to 4).

Can we please have the all filter back? Thank you.

The sort isn't pagination friendly. The sorted order isn't saved when visiting the second or third page.

I sorted the "Creator" tab in the ascending order, and it worked properly. The URL was https://stackoverflow.com/tags/synonyms?tab=Creator&dir=Ascending&filter=Active. (Notice dir=Ascending).

When I visit the 2nd page, the "Creator" tab becomes descending order. The URL was https://stackoverflow.com/tags/synonyms?page=2&tab=creator&filter=active (There is no dir=Ascending). Adding dir=Ascending to the URL manually solves this issue.


Thank you for the ability to sort the fields. I've been using SEDE to sort, and having it on the synonym page makes it really easy.

However, on the "Pending Approval" page, there is no way to sort the "Score" column:

enter image description here

I think the "Score" column is the one that needs to be sortable, as it would make it really easy for me to go through the list and approve the ones that have been upvoted thrice or something similar. (I get it that I might be the only one who uses it in that way, but it would be really helpful if it is possible to sort that column).


When you're on the proposed synonyms page and you're the final vote on a proposal (4th up or second down), nothing happens, just the score changes. If you refresh the page it will be gone, but it would make more sense to have something see if it was the last vote and hide the row, for a visual confirmation that it's done.

    +1. This needs to be addressed, but there's some nuance there - for example, how does undoing votes behave in this case? (This behavior is similarly undefined right now on the per-tag synonym page where you can technically undo a vote for a synonym that was approved, heh.)

    The sticking point here is that normally votes can be undone... but while final votes on tag synonyms (either to approve or reject) can be retracted, doing that doesn't undo the approval or the rejection. We're going to add a confirmation step here when a user is about to cast a deciding vote and provide visual feedback that the action took place.

Clicking on the tag in the "Target" column sometimes throws a 404 error

I noticed this on BoardGames.SE. There are tags that do not have a number after them. Clicking on them throws a 404 error.

For instance, clicking on [eldritch-horror-cities-in-ruin]

enter image description here

navigates to https://boardgames.stackexchange.com/tags/eldritch-horror-cities-in-ruin/synonyms, which brings up a 404 page.

Clicking on the tag in the "Synonym" column results in a normal page, albeit indicating there are 0 questions.

Clearly something isn't going right. At first glance, it looks as though a synonym exists for a tag that has been deleted. Not sure if this is related to your changes or not, but regardless, the dashboard is not behaving in a way that users expect it to.

    The use case here is a bit weird, but ultimately makes sense, I think. Just because the target tag was deleted, doesn't mean the synonym mapping in and of itself is invalid. Say the target tag gets re-created... if we deleted the synonym, assuming it was created out of need in the first place, we'd be missing that link and potentially even allow an undesired tag (the source of the synonym) to be used again. This is similar to how we don't technically delete answers on a deleted question in case the question is restored later.

In addition to being more widely advertised, I would really like to see this page default to Pending Approval requests, sorted by oldest first.

Retracting the vote by tapping on vote up button again changes the score but doesn’t change the button color from orange(?) back to grey:

Refreshing the page fix the issue:



I have some general feedback regarding the new dashboard which has made my processing of synonyms a little bit harder.

Let me tell you from where I am coming. I have spent the past 1 year playing around with tags (starting from June 16th 2018, barring the 3 month vacation that I took from Sep 15th to Dec 15th), and adding around 600 synonyms on Stack Overflow. Some days, I've been creating more than 20 or 30 synonyms, so I definitely am a heavy user of that page.

Today, I started this year's annual cycle of "Fun with Tags", and used the new shiny dashboard. My usual way of handling synonyms is:

  1. I open the master tag's page and click on "Synonyms".
  2. Type in the other tag's name and click on "see all synonyms"
  3. Click on "approve".

As you can see here, it was 3 clicks. Now it is:

  1. I open the master tag's page and click on "Synonyms".
  2. Type in the other tag's name and click on "see all synonyms"
  3. Click on the "pending approval" tab
  4. Click on "approve"
  5. Click on "yes, I approve"

which is now 5 clicks or almost double number of clicks as compared to the last time. This has caused a serious decrease in my productivity. I get it that I am not too fast usually, but this has made me a bit more slow.

Another fact that is currently causing a small trouble is the swapping of master and the synonym places. There is this problem called "muscle memory". I've been trained for the entire past year to look at the first column as the master and the second as the synonym. Swapping the two has messed up a lot, and does cause a bit of trouble. The process for creating a synonym has now been:

  1. I open the master tag's page and click on "Synonyms".
  2. Type in the other tag's name and click on "see all synonyms"
  3. Click on the "pending approval" tab
  4. Click on the "..." to get the swap menu in order to swap the two synonyms thinking that I've proposed it in the wrong order (muscle memory problem)
  5. Click on "swap"
  6. Click on "cancel" realizing that I have made a mistake
  7. Click on "approve"
  8. Click on "yes, I approve"

which is taking me a long time to get a synonym approved. My "Fun with Tags" episodes aren't being fun anymore. I see that you mention:

The "synonym" and "target" columns are reversed now, so the table can be read from left to right;

but has anyone actually complained that this was a problem? To me and to most of the users who've used the synonym page a lot, it was quite clear. Even in most of my meta answers, I've used ← to indicate that direction. I am not able to see as to why that created a problem.

Anyway, for this mistake I can take the blame. I will get used to the new one in the next few months, but I would still have to make 5 clicks to get a synonym approved.

Would it be possible to make this experience a bit smoother? Please? I do request you humbly.

  • 2
    I for one much prefer the "synonym -> target" order. I remember being confused several times over the years and this left-to-right order matches my mental model much better (e.g. "X maps to Y", "X will become Y", "X is an alias of Y", etc; all of these are more awkward to state when swapped). Muscle memory/habit is certainly a nontrivial consideration, but my bet is that the majority of people will prefer the "synonym -> target" order. Commented Jun 30, 2019 at 6:03
  • 2
    Once again, thank you for the detailed feedback! We discussed this internally earlier today and we're going to do two things here: we'll put the "All" view back in for moderators, and remove confirmation steps from Swap and Approve actions since errors on both are easily reversible by either swapping again or deleting the synonym, respectively. However, the order of the columns is here to stay, and I hope you can acclimate to that before too long.

As far as I see, many pages' redesigns have been made to adapt the page for any screen width devices (aka "responsiveness"). But the tag synonym page is constructed mostly of a table, hence there is no obvious solution for how to wrap the table row while leaving it in a single row. Without such wrapping, the page will be still unhandy to use on narrow mobile devices without repeated zooming in/out.

Here's how the page looks on my phone (current scale of this picture on desktop browser almost represents the actual, i.e. physical size of the phone's screen):

from phone

One possible solution was found on Wikipedia (scrolling the table horizontally, while whole page width is fixed):

scroll table

  • 2
    We currently don't have support for horizontally scrolling tables, but I dig the idea. However, even with that, we'd need to do additional work here to make the table itself usable - for example, by the time you scrolled all the way to the right, the context for each row would be lost, so we'd probably have to rearrange the columns. For the moment, we're going to stick with what we have due to time and resource constraints on the team.
