Looks fantastic to me, great job.
One of my main complains with the KMotionCNC screen are those jog buttons - I've made my own GUI that's cut down on that, but it's only really applicable for the machine it's driving (i.e. not a general purpose CNC GUI)
One suggestion though: PLEASE include an option for a metric tool setup. Having to convert my steps/mm and the like in the tool setup screen into inches seems amazingly archaic in this day and age!!
Very much looking forward to seeing this progress...
