We're considering adding favorite notifications to the global inbox, and are looking for feedback on the idea (as we're not completely sold on it).
But first, some history.
Favorites are kind of like bookmarks, in that they're kept in a handy centralized place. They also follow you across browsers.
Ok, ok... "bookmarks, on the internet" is not the most compelling feature, but Favorites also opted you into notices for those questions as if you were the owner (edits and new answers, at least). This was probably the most confusing part (though a requested feature) of the old envelope behavior judging by erroneous bug reports, so a way to opt out of this behavior was added.
Now, favorite updates go nowhere.
But we could* put them into the inbox.
Here's how we envision this feature working:
- Every current user has their "notify me on favorite changes" preference cleared (new users start with it cleared).
- The first time someone favorites a question, they're prompted to opt-in to favorite notices.
- Whenever a question is commented on or answered (or, possibly, edited) a new notice is pushed into the inbox of users who have favorited it, and have opted in.
Opt-in would be per-site, and it would remain possible to opt-out from your profile page.
This is not a final design, but the basic idea is correct
As I mentioned above, we're not 100% sold on this idea. We've had a policy to date that nothing goes into the inbox that isn't specifically targeted at a user; this would be tweaking that policy.
*We could also put changes into their tab on the user page, but that reduces their visibility.
