I don't have Next, and I don't plan on getting it, but I'm keeping an eye on the development of this "Commander". I hope it turns out so great that it'll launch by default every time the system starts up!
Actually, you can disable autoexec.1st by typing "D" when the help screens are displaying if you don't need them anymore, and put an autoexec.bas file with your own preferences in the /nextzos/ folder.
