Feature request: Indentation guides

[magikmw]

Thanks for an awesome package.

I would love to see optional indentation guides, especially for indent-mandatory languages like python.
More complicated code examples, especially when intended for training, could benefit from the improved readability.

Kludged example using github markdown:

function hello():
|   print("Hello World!")
|   print("more code")

hello()

That's actually a great idea!, might prove tricky to make, but I'll definitely have a look!
