Category suggestions do not work in Visual Mode still for me. I've typed up to 3 characters and nothing appears.

I noticed that the bottom bar was added back a few weeks ago while in edit mode, so is it possible to add back the old Category edit bar from the previous editor (where you just typed in a category name with no prefix)? I think it would solve some of your browser issue problems as it worked problem free before.
