[video] tag non effective in side notes.

Hi distrait,

By default WordPress does not process shortcodes within shortcodes (like [video] within [ref], so this is something that will need to be manually added to the plugin in a future update. I’ll need to iron out a few bugs before it can be made a permanent feature.

However, for now you can embed videos without using the [video] shortcode, either by writing the embed HTML on your own, or (more simply) pasting the video URL on its own line, like so:

[ref]Here's a video:

[/ref]

Again, this will only embed if the video URL is entirely on its own line.
