You should post a screenshot in the README to let the people know what the rendered PDF looks like.
There is an example in the repo: https://github.com/schicho/mdpdf/blob/main/examples/README.p...
(It's vanilla.)
I'd love to see an output option that leaves 40%–60% of the right side of every page blank, for handwritten notes after printing (similar to Tufte layout).
This looks like a great little utility. Nice job!
I would also like to see some markdown to PDF screenshot examples in order to properly visualize the intent. Keep it up!
