Yep. If you look at the feedback thread before this version was released, they legitimately did listen to feedback from power users and made changes.
The first beta version had all of these annoying quirks, but then they added a bunch of settings (Compact Mode, Quick Copy Actions, Wide Mode, Disable Animations) that after you change them gives you a solid experience.
Is there a way to get rid of the "Fill" button and make the whole entry do the fill action? That's what it used to be, and I have soo much muscle memory for it. I almost never want to look at an entry.
Nevermind, sibling had the answer: "Settings < Autofill < Click items to autofill from Vault"
Funny how I didn't even think to look for appearance settings.
