Allow users to ignore whole discussions?
Fielded a question from one of my users asking if there was within Vanilla the ability for them to ignore entire discussion threads. Obviously they can ignore individual users and un-announce announcements, but sometimes threads drag on and a user might not want to look at them anymore. There's too much community involvement to sink the thread for everyone, but it would be neat if a logged-in user could tick a box next to a discussion saying "Ignore this discussion" and it didn't appear at all in, say, /discussions/unread.
Might something like this be possible? I don't have the php ability to code up an addon myself, and I didn't see anything like this in the addon library.
