Has it been a nice upgrade feature wise for you or more of the same
Of course it all depends on what one uses their device for, for myself my Mini 6 is just a general browsing and media consumption device so I'm trying the beta with no set expectations and I don't really see much difference. I tried messing with the icon customization and ended up going back to standard since nothing really looked better otherwise.
I continue to think that command center on iPadOS is a completely wasted opportunity - it takes up just 1/4 of the screen and that's just plain stupid to be unable to use the rest of the empty real estate. So while it's great that those who want it now have multiple sheets for control center and can customize it, it's silly that there's so much wasted screen space on an iPad even one as small as the Mini. This particular UI limitation has always been a frustration for me; I understand that iPadOS is rooted in iOS but it has been forked for a while now and some of this stuff like huge expanses of unusable space in control center, widget slide over menu or the notification shade should not still be lingering around.
I do notice improvements in Messages and I'm sure there's other little things that are general improvements.
Everything else is just uninteresting to me - I don't use Notes much, nor the Calculator etc. I primarily stay within Safari, Youtube, Messages, Teams and a few other streaming and smart home apps and that's it.
