In most CNC software I’ve used, when the program has focus, a keystroke will cause the job to pause, which is nice if something is going wrong.
This feels doubly important for easel since during long jobs I tend to let my cursor wander and can’t move back to click the pause button before doing something stupid that breaks my bit.
It seems like it would be pretty easy to implement, and a world of help if we could assign the spacebar the task of pausing jobs.
