• Take the demo from existing gallery

I'm not sure if there's a right place to put this one. It's not Material, Cupertino, etc..

[rami-a]

I think we can put it in Reference Styles & Media

[guidezpl]

I thought it was 'Reference Styles', not 'Reference, Styles' that makes more sense now! :)

[rami-a]

TBH we should probably rename this section. There's no media in it. Maybe it should be called Reference & Styles. Thoughts?

What should the documentation link be?

[rami-a]

Hmm I'd say if there's any particular widget that is being used throughout the demo (like Transform or something) link to that, otherwise I'd say have no link (though you'll need to add support for no links being provided)
