Do you remember what the battery icon in System Preferences looked like in the first beta of Mac OS 12? It's a beta. Give it some time. It's not out yet.
I'm very doubtful that by the time it reaches release, they'll bring back the icon grid and the sensible layouts (instead of those stupid iOS-like lists) in the panes themselves.
Frankly, the icon grid was arranged somewhat arbitrarily to begin with. I'd be quite happy to have a largely-alphabetical list, making it much easier to actually find the specific preference pane I'm looking for.
I'm still running OS X (10.11, El Capitan), but System Preferences under that OS had a View menu option Organize Alphabetically. That was present in many (all?) versions of OS X. I don't know if/when that may have been removed.
Every time I would open system preferences I would just use the search bar to open what I was looking for. I think they should have just either grouped the icons better or let you choose. Right now the current layout doesn’t fit unless you make it bigger which is weird on my XDR when I can just make it longer …
