I like the questions, I feel they're a lot better now
but now that you've put options into everything, it's a bit limiting. the fact that I can't select more than one file manager is kinda goofy, given the fact that I can clearly select more than one operating system. furthermore, maybe I use more than one windows/mac OS? for a considerable amount of time, until I replaced it with debian, I had windows 7 on my laptop. while my desktop was windows 8.1. and after that switch to debian, I'd now have to choose between selecting the stock file explorer to represent my desktop and thunar for my laptop
