I think having the parts selector tell us which parts were mods would be helpful. Kind of like how the vehicle selector tells us which cars/configs are mods. Just a small idea but I think it would be useful.
I was gonna type a thread like this yesterday It would be useful because even when I am making mods, when it comes down to figuring out official tires from mod tires, well, that can be interesting sometimes
If I install a mod, then forget I have that mod on say, sleepy headlights and wheels on my 200BX, I could delete it and my car would look like it spent 15 minutes in Brooklyn.
Yeah, that would be nice. Also some sort of preview, so you see what you are installing. Having to wait for the car to reload, just to find out that the part looks horrible, is a pain.
