Review for Quick Folder Move by Mark van Renswoude
Rated 4 out of 5 stars
Use it on a daily basis! The only option I was missing is to always show the account name; as I have a few shared accounts and lots of folders, I'm not always sure if a folder is mine or shared when there is no duplicate. Fortunately this was easy to hack (simply removed the dupeMap check in the js), but a proper option would be awesome.
