I recently installed Ubuntu on my laptop as my primary OS (dual booting with XP) and I've just felt in love with it... still... there're many things I miss from XP and being able to easily configure my screensavers is one them.
So, after reading this, and other similar posts, I decided to try to do a full replacement for gnome-screensaver-preferences
After a couple of days I've managed to come up with an application that will let you (a) see the list of all your screensavers, (b) preview them in a small window and (c) change their settings.
The application does not yet support changing parameters specific to the daemon (such as when to start the screensaver, whether to lock the screen or not, etc...) but so far it can be simply used to setup your screensavers so they run the way "we" want them.
If anyone is interested, it can be downloaded form this address:
