Title explains most of it.
But to elaborate - Some of the armor pieces on frames are poorly placed. Not letting me get the most out of my fashion purchases. I would love to also make separate armor pieces bigger or smaller. Maybe even add a "Mirror Position/Size" toggle so I don't have to guess if I got everything aligned perfectly. Seeing all the customization that we are allowed for orbiter decorating. I don't see why it shouldn't be possible, just have a little box on the side like in Captura to open up the advanced menu and we get to work.
And as an example for the Syandana's; It would be badass if I could put my Uru Prime on my Frame's lower back to look like a cool tail. Or maybe on the back of the head for a hair-like motif. Would definitely add alot more fun to the act of Fashionframe. If there's any concern for clipping... Then honestly I don't mind. If I accidentally made something clip horrendously, then that's on me. And i'll fix it myself.
