Edit current download locaton

[GCRaistlin]

Now when an user selects "Set download location" he/she gets standard "Save to" or "Browse for folder" dialog windows. Actually, it's uncomfortably in many cases 'cause you have to go through tree folder again, even if you want just to change drive letter in torrent's path. It would be good if by selecting "Set download location" uTorrent shows editable dialog window with current download location where user could edit it or call standard dialogs from.
