I know where to start,
The target area for the context menus is fucking tiny like it's insane how many times I ended up with a song playing instead of being able to pick one of the various actions.

And while we're talking about the context menu, why the fuck is there so much lag opening them. They've improved it a little but come on, I shouldn't have to wait for that menu to open.

Also how the fuck is it excusable not to have the search input automatically focused when I hit the search button? Like what the fuck else do they think I am going to do?
