3rd is really the only feature I feel is missing and makes me wish other apps were as nice as yours, and they even have out put file problems... Anyway could you add an option to remove the so called "scene numbers" while trimming? You know the 3 or 4 numbers that precedes the game's name. Maybe also taking out extra info in the file names that are put in (parenthesis) like dump groups or hash values and fixing the spacing while keeping more important info?
So something like this,
1234 – Super Happy Fun Time Game (J)(v1.1)(Group)(123123123).nds
Becomes
Super Happy Fun Time Game (J) (1.1).nds
I was thinking the same thing. This would be awesome!
