Hi, thanks for the mod!
I just installed it, played around and wanted to delete all the text, leading to an unrecoverable error:
Error while running event m-microcontroller::on_gui_text_changed (ID 2)
m-microcontroller/microcontroller.lua:71: attempt to index local 'mc' (a nil value)
stack traceback:
m-microcontroller/microcontroller.lua:71: in function 'update_program_text'
