I've edited about 40 tracks from a 60-track-album. When I try to rename the files, I can't simply select all and use the rename tool, since 20 tracks can't be renamed to itself.
I now have to select the 40 edited tracks, which takes a lot of time - and last but not least it is error-prone.
So please let me rename files, although "there are one or more errors". You might raise a message "Do you really want to move/copy the files?"
Implemented in next beta.
