For anyone jumping versions: remember that Apple messed with the login keychain not being able to be backed up in the most recent Tahoe release [1], which means that issue will be around in Golden Gate.
The Tahoe Dock "App View" / Spotlight just lists my 30 installed apps intermingled with Apple System Apps, which I hardly ever use. Hard coded categories, no way to re-order as far as I can tell.
Seems like the closest thing to LaunchPad is dragging ~/Applications to the Dock.
The other thing I have noticed is scrolling in Firefox is more choppy, and animations are more Janky than Sequoia on this old MacBook Air M1.
iOS 27 is pretty good though.
