1. Hm. It's an interesting idea, but I doubt it would be added; it'd be very harsh for early game when nobody is having kits yet
2. some background framework for sounds is added and sound will most likely be coming
3. this is also planned
4. ...eh- kinda goes against the "random generator" feeling? where the game might pick a main character or five for you. might be a good mod idea though
5. there was a "remove accessory" button in an earlier version, and it'll most likely be coming back.
