I woke up at 5 this morning and couldn't get back to sleep, so I started visualizing nodes and what I could do to get Easy Beaches. You know, import clip, attach a few links, set water level you need, et voila, your beaches appear at water level, customizable size/distribution, and having a mask for the white sands as well. And they stay (or rather move to other altitudes) when you raise the water level, or reseed the terrain. Now I have to remember what I figured out in my half sleep and get it to work.....
