Hi Tom,

...

 Another would be an unfilled-density tool for cryo-EM. Even something as simple as masking out everything within ~1.5A of the existing atoms is a great start... better, of course, would be to generate a proper simulated density map based on the model and then subtract that, but that's a much more challenging problem that would first require me to have some level of B-factor refinement in place.
