Not that it's 100% bad. Ability to fully disable the show desktop region at the end of the taskbar, the combined volume/network/quick settings icon region, the general redo of the popout for quick settings, the search not being larger than everything else in the taskbar by default, the notification region merging with the clock region, and the general styling update are good. It's just heavily outweighed by the bad... and the broken.
The still broken even though they rewrote the whole thing including things like the new menus often getting stuck open even when you click away from them, auto-hide taskbar on secondary monitors still having issues popping up, the start menu always opening on the primary monitor when you press the win key even when you're active in another monitor, the new "Chat" Teams client that integrates with the taskbar still not supporting corporate accounts, sudden rapid fire 1 by 1 bursts of notifications about the emails I've gotten and already responded to in the last hour despite focus assist being disabled, and I'm sure more I can't think at the moment.
Also the dislikable additions which are of course preference based but I think most people will find things that received a lot of effort like widgets and chat useless.
.
All that being said it's still livable for me but it is a definite downgrade and a bit disappointing.
Hopefully, RaMMicHaeL will be able to fix that: https://rammichael.com/7-taskbar-tweaker-and-a-first-look-at...
The auto-hide functionality is actually a smidgeon better now, not reserving space anymore (on Windows 10 I have to use ButteryTaskbar), but I want to disable the useless 2-pixel (or whatever it is, haven't measure it) border and the mouse hover to activate it. I'd also prefer to have it oriented vertically since I use super ultrawide monitors (49"), but can live without it, even though it's a regression since Windows 95 (or 98?).
Also, you really have to disable animations because the animations are sooooooo sluggish. I always disable those OS-wide anyway though.
