Ideally this one click would remove all plots from a beacon that contain 0 blocks (assuming they aren’t required to connect pieces of a build and that they aren’t cleared land/foliage that could regenerate if unplotted). This way you could plot away, then build, and once the build is done, click “remove air spaces” and get back any plots that are unnecessary. Maybe even get back plots that are unchanged compared to the original landscape. Shouldn’t be that crazy hard to do.
It might also help with compactness.
