A few changes I would like to see
Larger graphic for us old farts with failing eyesight, about twice the present size.
A text line at the top showing the name of the file that's currently loaded.
A type in box as well as the slider for entering the advance and injector time.
Different bar graph object for the sliders that can't be changed e.g. temperatures.
General comment:
I think Cliff could use some help with documenting, it's very hard to do well when you are so close to the project.
Oh, heres my pet peve, it's hard to get the manuals, assembly instructions etc to print out without loosing part of the text (RH side)
I think this is a North American A4 paper size issue.
