I'm using Notepad++ to edit text files for a program called Nastran.
Nastran uses a very strictly positioned "card" language, so that each card takes exactly 8 characters wide.
It'd be helpful to have a vertical guide every 8 characters like EditPlus does.

Can you implement this feature? It would be super useful for my jobs and many other Nastran users in the world.
