The audio panel is definitely an issue, but Ear Trumpet solves it. I know relying on a third party solution for a system function isn't ideal, but Ear Trumpet is too good.

Idk, I like the new start menu, especially once they added folders to it. I rarely need to see everything in my start menu and having my most used stuff right up front is nice. The only thing I wish is that I could completely get rid of recently used files on the bottom half.

If the menu nesting is referring to what you get when you right-click something, then yes. That can die in a fire. I don't know who thought that was a good idea, and it's wild because many people thought it was. Something like that doesn't make it to production before passing teams of people.
