How to Browse openSUSE's Source Packages

This works for a long time but I don't think that it's widely known: you can browse/view/download all the latest patches of openSUSE development in the openSUSE Build Service Factory project (yes, you have to login). That's more comfortable, comprehensive (3000+ source packages) and up-to-date (real-time) than me dumping our KDE patches once every release somewhere. :-)
