Feature Request: GCode simulator in the window

[gremlin529]

I really like gSender, but one thing I'm definitely missing from open controls is the ability to play a simulated run of the gcode in the window and see what the machine is expected to do when it runs.

that would be handy. but I find thats why I like Vcare as it simulates the cut. but Im sure everyone doesnt use Vcarve
