Make the Move feature auto-complete in the Windows client (like the Mac client)
Move | Other Folder... pops what looks like an Office 2003 "Move Items" dialog. There's no way to find a folder expect to navigate all the twisties and remember where you put whatever it is you're looking for. Daunting, high-friction, every time.
On the Mac client, you're dropped into a Search experience. Wildly more usable.
