Support for connected style proportional editing in UV editor. Now when connected proportional editing is on, only UVs on the same island will be proportionally moved. The implementation simply rejects UVs whose island does not belong to islands of selected vertices and decrements the total count of transform elements appropriately. Memory usage could be better but it would require some more preprocessing.
