Maybe I'm being stupid, I have no experience mapping, and I KNOW I'm bad at searching so if this has already been rejected, I couldn't find it. Anyway, I understand that having two objects at the same time would be impossible for mouse players and would probably never be allowed in ranked maps even if it was just sliders and not notes. Still, as a touchscreen devotee, I think it would be fun to just have double sliders since it wouldn't be hard to hit them accurately.
