… is the little Time Machine icon in the menu bar. It saves a Dock space as I can access everything I need to do with Time Machine in a much more compact way.
The new Stacks stuff is nice, but while I use Stacks, I don’t use it for collections of enough items to warrant using the new list view.
One thing I might like back, though, is the ability to put an icon for my home folder on the right side of the Dock that with one click opens ~ in Finder. Yes, I know, I could click the Finder icon at the left, but that works ever so slightly differently; it might focus an existing Finder window.
Did anyone else notice the TM backup done straight after 10.5.2 took ages to ‘prepare’? I understand why, because there were a lot of individual files that changed in the update, and it had to query the FSEvents database to list all those changes, but I wonder if anyone else experienced that step taking 20 minutes or more.
