MP3Tag is simply wonderful, but I suggest a little improvement.
Many times, I have to test "trial-and-error" the format string that work best to obtain the desired result.
Time after, I'd like to apply again this "well tuned" format string but frequently I have to search this format string that is listed by the combo together with many other format string (less useful or simply wrong).
A useful feature would allow to label all useful format string (to easily find them), and to delete all useless format strings.
Thank you again for this very good software!
