Thank you. Committed.

A little side note, valid also for the ColorSchemes module (and for all the 
future modules): each NSPreferencePane should implement -shouldUnselect:, a 
method that returns a NSPreferencePaneUnselectReply value that let the 
SystemPreferences application know if the current active pane is in a state in 
wich it can be closed without loosing any information. That is, if you are 
editing someting and the new values are not saved, your method should return 
NSUnselectCancel.
Moreover: if your pane shows windows, dialogs, etc., you should implement also 
-willUnselect and close all your windows here.
An example of use of these two methods is in the MDIndexing pane of GWorkspace 
(GWMetadata/Preferences/MDIndexing.m).
