This is an awesome feature, thanks!
I have 3 main comments off the top of my head:
- Code blocks look pretty bad
they are too wide and don't quite fit well with the aesthetics. See here

- LaTeX is a must for me. I do lots of work with equations and algorithm development. So much that this would probably be the main use case of Tana Pages for me.
- Adding RSS to Tana Pages would make it super easy to publish blog posts to an audience from within Tana. No need to use Substack or any other platform. Read, write & publish all from Tana.
I was thinking GitHub embeds would also be great.
