We're still slowly working on new features. I'll post new things as they arrive here.
First on the list: youtube embeds! Just paste a properly formatted youtube url and it will appear as an embedded video. If you don't want it embedded, you can put it in a code block or a named link, like so:
`https://www.youtube.com/watch?v=b0jqPvpn3sY`
https://www.youtube.com/watch?v=b0jqPvpn3sY
[youtube vid](https://www.youtube.com/watch?v=b0jqPvpn3sY)
Url styles that will get transformed:
https://www.youtube.com/watch?v=b0jqPvpn3sY (https:// and www optional)
https://youtu.be/b0jqPvpn3sY (https:// optional)
Contrary to popular belief, I have no clue what I'm doing.
