Thanks! So there aren't any GUI controls, buttons, input fields, &c.? Would there be a way to add those in the future? I'm really fond of Oberon (printed out the entire manual and read it over multiple times when I was younger and probably still have it somewhere), and Lua has worked well for me in lualatex: https://tex.stackexchange.com/questions/723897/breaking-out-of-recursion-in-latex-macro-using-lua https://tex.stackexchange.com/questions/723897/breaking-out-... so this seems like it could potentially be a good fit. My next project is working up a programmable drawing program and I'm still trying to find the perfect language and GUI toolkit....
