I have a similar issue with one Mugen game. LB imports 53 files from the sound folder for some reason. I want to leave 'Automatic Import' enabled for Steam games and the like, but every time I delete the extra entries, close and reopen LB, they come back. If there was a way to either tell LB to exclude certain file types or if we can specify any folders that we don't want it to scrub for games, that would be a very helpful feature.
