Dabdab was designed to allow to keep notes in a simplest way possible, which also means as little formatting as possible. Markdown does a good job there, but there are cases that still need some additional help from the service side to make them effortless, one of them is media links.
From now on you can simply mention a youtube link and it will appear right next to the paragraph it was mentioned.
If a paragraph contains just one link, it will be totally replaced with the video player.
Dabdab will make it's best to avoid being intrusive and still be helpful when possible. Stay tuned!
