You have texture sections for 'scratch' and 'edit', so why not the same for models, considering we have a MASS of model edits and the geosetmerging craze. Before the model gallery gets tainted with lazy model edits.
Well, personally, I am sticking to scratch models, or anything I have skinned that isnt scratch built for textures. Most of my edits are fully reskinned, so would be thrown into textures.
