Let me start off by saying how much I love your program. It's simple, straight forward and works very well. 
I have a few suggestions:
-
When renaming many files, add a check box for remembering what I selected. For example, if I am renaming my files to temp\%artist% %title% it would be great if when the alert comes up that says File exists, Abort, Ignore, etc, if I could check the box to say do this say action each time.
-
Simple duplicate checking. Nothing complex. I would match just a couple of items: bit rate, length, file size, and if the name or title matches. It would be great if it would just do a quick highlight of the tracks... then I can go in and remove the ones I want.
-
Get track info. I have tons of mp3 without Genres, Albums or Dates. It would be great if I could select a single track and get just it's missing meta data.
Thanks all from me... great job guys... I also posted you on my foss list (http://www.synergymx.com/foss_list.php).
