I think this feature would be very nice as well ^_^ I'm not too fussy about drag and drop, but it would be great if you could select multiple controls at once and move them together. Lately, I've been trying to keep my menus small, but huge scrolling control panels do happen afterall (To me at least) X_^
Still, unless you accidentally reset it by unplugging the Result component a lot *raises hand*, sorting isn't something you will do as comparably frequently I'd imagine to other things in Filter Forge so perhaps not as much of a priority for now. Still, something that would prove quite helpful to creators who... um... accidentally create too many controls *raises hand again*.
