I know that I can run "kill -STOP" and "kill -CONT" to halt and resume a process. But I can not find anyway to easily do this with a GUI. This seems like a very powerful feature, I am surprised it hasn't been implemented. I'm looking for something like "xkill -STOP" or "xkill -CONT"
(I've been using halt and resume on Firefox while I'm running of my battery to save power)
Any suggestions? Thanks
