Yes, to an extent (though note, I haven't tested anything beyond forums, I don't own other apps). All apps that support tags/prefixes should make use of the prefix formatting, and should have the separate prefix dropdown input, no changes needed. They will not have all of the special forum settings (tag mode, default tags/prefix, require, etc). I have plans to extend those settings to all tag-enabled containers, but that will be some time down the road. The app does not change sorting/filtering options at all. It'll behave the same way it does in a vanilla install. You can click tags and prefixes, and it will take you to a search for all content having that tag/prefix. It will not filter or sort within the forum directly. This app allows you to override the tag mode on a per-forum basis, so you can have it closed in one place and open in another, and it adds a 'prefixes only' mode. Currently it does not let you change the minimum/maximum tags per forum, but I'll take that into consideration. Thanks for the feedback.
