Mechs are great, flying around in space is great, exploring star systems is great. Space Station trading is good, but could be better (for another post). I understand this request is a little more labor intensive and involves ui and art changes, but the suggestion itself it simple. Please add feature analogous to armor cosmetics for mechs. (Some might go so far as to request color customization per slot, but I'd be fine without it, keeping the uniform look.)
I'd get behind this idea. My favorite-looking mech parts definitely aren't the best performing, so mech cosmetics would be a great feature for me.
+1 Cosmetic slot for core, boosters, and legs. Not for weapons though, that would not make any sense. Unless they are identical in function like the saw and sword. Also +1 to your thing about the mannequins for them as well.
Agree that cosmetic slots really apply most to core, legs, and boosters. Arm slots isn't what I had in mind.
