This was an interesting blog to read through!

When you are rendering markdown though could the # h1 change the font size of the application as well. I think so that it is/possible within your application.

I had once created a very basic text editor prototype in terminal which could focus on markdown and the foreground-background color options and one of the limitations that I felt at the time was that I couldn't change the font of certain texts

So I would like to know if could this be used to change the font of certain text within the terminal

Thanks and the project looks cool!
