Thanks guys. @shinra358, that extra level of organization makes sense; I like that. I'm currently working on filtering for the other types of data at the base level, so at least you can filter by genre, status, etc. instead of platform if you need. That I can see coming next.
The background image darkening is already controllable in Options. I added dimming when idle to my list; the other items are all planned. Big Box is supposed to be work with hotplugging like Retroarch; have you checked the box to "Enable all attached controllers"?
@MrSirrr, good idea on the triggers. But yes, we definitely need a way for faster navigation. The page up/page down buttons should help, but you can't hold them down, so I at least have a fix for that on the way.
