BIG UPDATE!
I've worked out some updates and a new visual editor for the gui system.
To use the gui just download http://pastebin.com/Dfgc6z0T to a computer as /lib/gui.lua and try your best.
If you don't want to fight with the placing of elements on the screen, then you want to use the visual editor.
It's alpha state, but i hope it will make no errors.
The editor will create a full lua code as frame work for your own program in resolution 80x25 like for a tier 2 screen. But you need a tier 3 screen to use the editor it self. The program you can run then on a tier 2 or tier 3 screen.
Please try it and let me know, what you think. It's a bit flickry when updating the screen, but i hope i get this fixed.
You can download the editor at https://pastebin.com/jdaM8FKG
If you like it, let me know and tell me, what i could change, or what you want me to put into the gui or the editor.
