I often download several new Re-Volt tracks at the same time, but generally only enjoy one or two of them and end up deleting the rest. Therefore I have to quit Re-Volt, go back to my game folder and try to remember the names of the ones I didn't like and remove them. When you have a lot of new tracks you've only played once or when you simply have over 100 tracks like I do, this can be a bit tricky, especially with the lack of easily viewable track banners in desktop file explorers. Some tracks also have confusing folder names, which doesn't help.
It would be nice if a track could directly be deleted from within the game. If you didn't enjoy the track you just played, simply go back to the track selection window and delete it. Some sort of confirmation box would probably be good user experience at that point.
Thanks for considering my suggestion!

Cheers,
