Add indicator then file is moving

[gymka2]

Add indicator then file is moving. eg. there is torrent 30gb and i want it move from /dev/sda to /dev/sdb, deluge has feature to move change file location, so i'll and use it. i choose new destination and file move begins... is it really beginned? is it finished? is it still in progress? user don't knows about that progress. User needs indicator which would show current state of transfer. if file is small ofcourse everything is fast, but if file is big it takes a lot of time and if i shutdown computer or deluge in progress next time i'll need to wait while deluge rechecks that file. My vision of indicator: in progress column, in current state of torrent "Moving percent_of_progress%"
