The more i play KSP the more complex my constructions get. I recently built a shell for an inline cargo tank out of large radiator panels f.e... i see constructions here on the forums, using undeployed solar panels as "equipment boxes", retracted landing gear, air intakes and wings as part of a custom hull design and so on. This all looks quite nice, but in most cases, noone wants the function, as some of them wont allow it, to use KSP inputs as they were intended (or you just dont like it, like in my example... i dont want my cargo protection hull to heat up...).
An option to select between "functional" and "structural" could solve this. "Functional" would allow for intended use of the part, while "structural" removes all functionality from that specific part, being nothing more than a good looking part of a complex vessel (and by this, saving processing time and memory).
Do we need this at all? Do we want such thing to be stock, or would that be something for a mod? What do you think?
