Hey Cathy,
Thanks, I’m glad you like it!
Good suggestion, that would be a useful feature indeed. I’m not sure what UI would be suitable for that yet, though, as you would probably want to be able to assign other taxonomies (not only categories, but also tags and custom taxonomies) to posts as well. So I’m thinking about adding a second dropdown for the taxonomy that you want to change, but that’s an extra step in the editing process.
Also, I’m wondering whether it wouldn’t be good to also be able to remove taxonomies, but that makes it a rather complicated process indeed.
Either way, I’ve created an issue for this in the GitHub repository. If you’d like to pitch in on these issues, I’d appreciate a comment either here or at GitHub :-).
