Still cracking away CodeVideo, a way to create software educational content in a declarative manner.

I was recently inspired by the feature set I saw at Scrimba, so we just added slide functionality! The blog post is here: https://codevideo.substack.com/p/introducing-the-slide-displ...
And an example video is here: https://youtu.be/1duE604MGHs
It definitely has not gotten the traction I'd expected, but at the very least I'm very close to start making my own courses with it!
