== Integration of GHNS for GIMP ==

 Though you can add more brushes, patterns, gradients can be added,
Most users, not even pros usually add them off the internet. This is
so as there is no architecture to quicky share/add from a centralized
repository. This seriously limits sharing of resources among the

 GetHotNewStuff (GHNS) could probably help out here.
