This is a long-term plan for how to handle configuration in ROX.
Road map:
Note: Just to be clear on this: the idea is not to centralise the user interface (regedit, etc), but only to rationalise the storage of the options (they already get saved outside the applications). Whenever this comes up, someone suggests having a 'control centre' application where all the options for all applications go. This might be a fun programming exercise, but it's terrible UI, rather akin to moving all the light switches in your house to a single room (neat, but annoying).
So, if you're looking to configure ROX-Filer, you'll still get to the options through the ROX-Filer application directory (the same object you use to run it, read the documentation, etc). Separate configuration applications should be created only where there isn't already an application obviously associated with those options (eg, the default font or screen resolution).
2004-04-13 All the XSettings options have been moved out of ROX-Session and into a new python applications, which communicate with ROX-Session using D-BUS (which ROX-Session now starts on login). Find them in /uri/0install/rox.sourceforge.net/apps/Configure.
