On the setting menu overhaul, first thing I thought of was being able to manually zoom. Lavas and BA healing are two things that immediately pop into my head where I know it's used in the side panel. Also having brightness in the side panel is nice to see real time changes in game, but I suppose that's not too different than roofs.
Yeah, we'd keep the key important settings on the side menu, ones you need access to potentially whilst in combat or similar.
