Chris,
All caps or mixed case doesnt really matter to me. I'm dislesic so reading has never been my strong point. I used to send emails out in all CAPS because I had a drafting job and everything was in CAPS. It is kinda funny that someone decided to read aloud in the office one of my emails. I read the same in any case. You are doing the work I am just adding my opinions.
Restarting a program by line number or arrow selection is good either way also. Both options would be best.
Blinking Estop label will be nice.
Jog wheel (MPG) 5-10% per click up or down, for overrides. and a touch screen button for hand jog wheel control. The Haas control has it as a button for 100% -10% and +10% and HAND CNTRL FEED. IT makes sense to me to just have the MPG for over ride control and not have all the extra buttons. Simple is better until you loose functiality.
