Doesn't support well resolution and aspect ratios. Previews depend on authors 1920x1080px 1.77777 ratio and his mouse sensitivity. The way to get around it and get reasonable previews is to disable the deformative downscaling that ignores aspect ratio and setup your own mouse movement based on your resolution and mouse sensitivity. No option to generate preview only for one skin. No FOV option, neither AC showroom seems to respect it in it's cfg. No direct camera positioning.
57MB for a simple UI app... either it has 10million lines of code or the Node-Webkit takes so much ridiculous space to make an executable.
Usable but I fear the day it crashes and messes up the whole AC and I'm gonna be looking for back up files to revert the mess back. Haven't seen any back up files so far either.
