this isnt my thread, but an "all safe home" button would be nice to have, where the "Z" raises first and then the X and Y return to home. This is especially handy in the event of a broken tool (been there, done that

). Of course it would need to stop running the G code first...
Another neat feature would be a "run to line # _x_" button. This would allow you to run a program to a certain spot, then pause long enough to make sure the measurments are correct or the work is perfectly centered, ect. before continuing to run the G code.
I understnad that real estate on the program face is limited, but having an easy way to jog all 3 axis' would be nice to have also. Having this option would eliminate the need for the previous suggestion by allowing you to manually type coordinates and then have the machine go there to check for proper position of the fixture for the code you are running.
