One feature i'd like to see would be the ability to check the casing of track titles and prompt to automatically change those that are incorrect.
Look At The Sun would be changed to Look at the Sun or...
The Sun And Me would be The Sun and Me
MediaMonkey has a similar function under scripts but i thought it would be a good idea if it were built into mp3tag.
If this were also heavily customisable like everything else is i can see it being great.
Thanks for reading.
