I love OS X 10.8.2, but there are some improvements I'd really like to see. Some are very minor details, because everything else is great and I don't stop until things are perfect. Almost perfect means things can still be better. Messages app should work flawlessly (right now there are some weird things occurring every now and then where u see old messages and whatnot). Two-step login, see all logged in sessions/computers/devices and remotely log them out, change iCloud/iTunes password in a centralized way without having to re-enter it everywhere). Very important given how if your password is compromised, your Macs/devices can be remotely wiped if Locate My Mac/Device is turned on. I use Spotlight to launch/switch apps with the keyboard. Cmd+Space, Type a few letters, Enter. This works great for all apps, except Finder is not there. This slider snaps to the notches, yet it's 1 pixel off. Yes, very minor, but fix it and I'll be happy! This is my biggest woe. Using Mission Control with "Group windows by application" on, you can *expand* a group of windows. Yet they still overlap! Why? If you turn off "Group windows by application" they don't overlap! That behaviour should be mimicked. See photos. Group windows by application on, Mission Control performed. Group windows by application on, Mission Control performed - and window group expanded. See how they still overlap. WHY?! Group windows by application OFF, Mission Control performed. See how they don't overlap! This is how the previous screenshot should be like. Just wanted to vent, thanks for listening. I hope Apple figures out these problems and fixes them.
