I feel like the quick shift should cycle through your custom order. Other than that this was really fun to play around with, especially with modded characters that can act out of freefall you can do some pretty crazy shit.
This is such a big improvement from the classic version. The animations for switching character are pretty nice looking, and I love the new menu too. The only thing that I would suggest is maybe giving an option to turn off the transparent skin color. But aside from that this is great and I can't wait to see what else is store for this mod!
