Hey, I was planning to rework it in the scope of https://linear.app/a8c/project/post-settings-and-publishing-next-steps-ecf77520ab3c. It's great that you decided to address it, but I think it needs to largely retain the current UX where you enter the tags using a text field that automatically becomes first responder when you open the screen and uses auto-complete to add existing tags. You should also be able to add new tags from this screen by simply adding them to the text field.

I think the only option how we could improve the current UX is to add token fields to the text field to make it easier to remove the tags you don't want.
