to complain about the Mac operating system.
1. The "open" window in an application doesn't work just like the Finder, letting you copy/paste/delete files when you're scooching around.
2. The default action for moving one folder to the same location of a same-named folder elsewhere is to replace rather than to merge the two folders. What? To do that you need to buy an application like MoveAddict for OSX. Right. I know.
