What do you wish the X Carve controller could do?

It seems to me like a lot of our community is interested in modifying their machine. With that in mind, and disregarding any possible issues of cost or technical difficulty (within reason), what do you wish your X Carve controller electronics, or the newer X Controller, could do but cannot? One thing that comes to my mind is monitoring motor temperatures with selectable max temperatures for automatic job pausing or shutdown.
