I think it would be cool if you'd be able to enable/disable/remove/preview Userstyles from Commando. So you search for e.g. "Hide quickstart" and there's an Userstyle in Commando Packages scope that you can enable
Note: imo it should not affect user's color scheme in any form but being applied over it, like:
- Komodo's CSS
- Color scheme's CSS
So it's independent from what color scheme an user uses.
