Thanks! Does this work at a 'window' level? I ask because I can still
move the window, but can do nothing inside the window.

The kate window may be running multiple PIDs in a parent/child
way. If I do kill the 'parent' kate PID, would that also kill the
children kate PIDs? If it would, is there a way to keep AND access the
children, and just kill the parent?
