This is certainly useful, but I wish there was a way to edit posts that have been shared with me.

History would be nice too, IMHO.

Yes. I'd like to see this supported as well. The project is open sourced at https://github.com/gristmill/marked so of course a pull request is always welcome but I hope to get to both these featured soon.
