Actually, I think that I am inline with the other RFE listed for redhat-config-packages... but I would suggest a search box, and have redhat-config-packages also feed off of the source.list and headers that are listed in up2dates list, and do network installs via yum also. I mean Up2date is going to be responsible for updating these packages anyway. (I apologize if these changes are already made or considered, as I have not looked at the changes to redhat-config-packages in cvs)
This is part of the plan for the new UI.
This report is filed against a product which is no longer supported. It is very likely that the problem is resolved in the current version of Fedora Core or scheduled to be resolved with the new system-config-packages scheduled to land in Fedora Core 5.
