Comment 33 for bug 24280

For me, two best solutions would be:

a) Advising a user that automatically installed themes affect only to user account and won't be selected for administrator accounts.

b) creating an option in the appearance configuration dialog that lets user install a theme globally and select it (obviously this button will launch a gksu dialog asking for root password)... "install to the system" or something like this...

Thanks for your interest!!!
