I don't see any problem with this feature :) setting a command is ok- though
what i think would be better is to have .desktop files with the screensaver
commands and then just select from ones (maybe of Type=Screensaver) so you can
pre-package configs for xscreensaver and other screensaver 3rd party apps out
there.
