This is a quick and dirty project I threw together one evening after reading

It’s a editor with live markdown preview. Three versions exist, one without possibility to save notes to local storage. One with the possibility to save notes to lcal storage and a hosted version.

The thought is that you can save a bookmark with the editor embeded using

data:text/html, {contents in index.html}

or save it as a file on your computer if you don’t want to use the hosted version.
