Kerbal Space Program

Having more categories is a godsend, but some of them are quite large still and I think ideally none would require a scrollbar without mods. I suggest splitting wings/control surfaces from aero into their own category, airbreathing engines into their own category, and liquid fuel-only tanks into their own category; this way, plane and rocket design categories are more separated and there might be less confusion between rocket fuel and normal fuselages.

Also, maybe parachutes could be moved from utility to aero after moving out wings? It would make utility a little less random and even things out I think.
