I've created a quick 70sec demo:

I hate the sound of my own voice, but had to be done :)
The most difficult thing was trying to reduce down all the features and unique use cases; so I've realised I'll have to create further demos and tutorials on specific aspects. Sharing / Posting / Exporting to other #toolsforthought etc...
More coming soon.
