How to link from docs to videos? about textual HOT 2 OPEN

Something short of embedding a video player.

Perhaps a thumbnail in a callout?

Why not embed the video, especially as a thumbnail would take up a similar amount of space anyway?

 ## Stopwatch Application

from textual.

Tom's suggestion makes sense in places like the stopwatch tutorial where there's almost a 1:1 correspondence between the written docs and the videos.
In many other places, I've just recorded random bits & bobs...

Other things we can do:

• add a fairly discrete “Watch our short video about this” next to topics covered in videos as well;
• for the reactivity guide (and possibly other guides in the future) make sure the topic playlist covers everything and then add a similar thumbnail to the playlist saying “This guide has an accompanying video series here:”

(For reference, here's the textual reactivity playlist: https://www.youtube.com/playlist?list=PLHhDR_Q5Me1POyvjxq0lupFbrUrJeWTAY)
