auto-preview editing experience

[chadwhitacre]

I want to full-screen and have markdown on the left and an automatically-updated preview on the right. The two should be synced wrt scrolling. Preview should exactly match site.

@idan Is this a feature you're interested in?

Nifty feature, but definitely in the "later" pile.

🤔 Is still an issue?

This still something you would want to implement? (Someday)
