Add character highlighting to RLC to make writing easier and more intuitive, just like a real code editor
No need to make it very complicated, just make the variables, functions and symbols have a color difference on it

Hi, I'll put it on the list to consider - but frankly, I did something similar for the 1.16 port of the MineCoprocessors mod (1.12 version by Torocraft). It is really a big deal maintaining such a UI element for the ever-changing Minecraft and Forge versions. So I may also consider not doing it for the sake of my sanity ;) Cheers,-
