Hey Dustpuppy..
I seriously like your design..!
I currently implementing a lot of computers to control our energy, economy, item, shops, farms, trains, roads and a lot of production and storage systems.
Your gui is exactly what I'm looking for, I was developing my own like you. But time constraints in the family aspect of life has left me searching alternatives.
Would you be so kind to send me the code for that image you have attached. I know I can create it from your code, but again. Time is not on my side.
I will let you know if I run into some bugs/errors, new features etc...
