e) Visual Effects;
these are already in one menu (module) , so you just want to add
g) Splash Screen and Login Screen;
to the existing one :) and...
and....in each tab must be at least 2 button.
The first button "Install" that can import the file from each folder and the second "Delete".
improve it a bit the behavior
Besides I propose for some tab (themes, icons, Screensaver, Splash Screen, Login Screen and other) a third button "Download" for download the object from certain source (gnome-look.org for example)...and if you think that can be useful a forth button "Preview".
i saw the download button from kde, i think that is a great idea, it would make getting themes a lot easier (since no one has to go to the web page)
it could even have pre-made sources list that could change with online pop ratings.
So the list becomes even shorter in the Preferences.
The label name could be Gnome Appearance Center.
I hope I have brought something useful.
