first, thx for sabayon generally!
Im looking forward for a saybayon control center. if I know one of my friends start with linux I allways reccomended linux mint before cause they have a user friendly control center for linux newbies.
if sabayon do creates its own I think the community can enlarge and many beginners would be happy with sabayon.
I would even use the control center for my own...maybee even install on gentoo!
have a nice day
