Because terrasync doen't "do" areas which are only open water, we end up with all these white or red blocks in the map. Is there an easier way of filling them with water (unknown) colour than creating empty folders?
It would be nice to be able to center the cross-hairs on an empty block, press a key and, voila, it is filled with water.
EDIT: Creating an empty folder doesn't work. Terrasync has to, which it doesn't.
