Thanks for a brillant program.
It would be useful when creating playlists to be able to drag tacks up and down to get them in the correct order and also to have a column that showed the total running time from the first track.
For example, if each track was 2:30 long, the value for the top track would be 2:30 the value against the second track would be 5:00 and the value against the third track would be 7:30 and so on.
PS: I do know that you can see the total time for all selected tracks at the bottom of the screen.
He obviously refers to my suggestion to use ALT-Key and mouse.
So he wants to have a button, which enables an "ALT-Key-Locking" for extended sorting sessions to avoid overtiredness or spasm in a finger of the left hand.
