Tag synonym suggestions are starting to explode. It would be easier to vote if I could have a single page that filtered out suggestions I've already acted upon or could not act upon (i.e. my own).
I have just made a major couple of changes that will greatly simplify this.
We have been noticing a large volume of invalid suggestions, to combat this:
I changed it so you need a score of 10 or more on answers for the tag, to participate in the tag synonym creation process (proposal and voting)
I changed the "suggested" filter on the UI to filter out all suggestions you are unable to vote on. (note: it will still show ones you have voted on, but the list should be pretty small - so I do not anticipate this being a problem)
I think this will greatly help dealing with this.
Something different, I personally hate the UI of the synonyms overview. I'd love to vote some of them, but to do that I have to click every master tag open in a new tab (because there's no link to go back to the synonyms page other than the browser back button). That's too much clicks forward and back. It would be a great improvement if the synonyms overview itself also contains the vote buttons in the synonym column.
I would like a page that showed all tag where I have answered or asked a question that includes the tag on at least one side of the synonym.
I cannot give good input on tags I have never experienced, so would like to direct my efforts to where it is most useful. Ideally the page should be sorted to the newest proposed tag synonym is at the top.
