In all my life I've only experienced one UI overhaul that I considered an improvement, and even then there were a few specific features that were a step backwards, even by proper design standards (the same action did two different things in only slightly different scenarios.)
Buuiuuuut I know half the time it's just because I'm used to the old way, only the other half is it some corporate bullshit trying to push a feature no one asked for.
I can't believe you moved a button. HOW COULD YOU??? I trusted you, Patrick.
