Community Specific #Tags for Posts

I think it would be great if we could have Community defined tags that users can select from a dropdown when they make a post.

A bit like Flair but better.

These tags would be searchable and be used as content filters.

Blue pill shaped buttons with the #tags names could be added at the top of the community to quick filter posts below.

And maybe the ability to submit tags to specific community admins for review.
