We’ve added a few new demos to https://demo.crossbar.io.
The additions are:
Form edit - live sync of edits to list/details view form
Visitors counter - a Web component for easy integration into any web page
Video control - control an HTML5 video player in your browser from your mobile
Live Dashboard - some widgets for live display of data
Take a look, maybe you find something to inspire you, or that you can use.
Also, the demo instance has now been upgraded to 0.10.4 - so you can use this again with current library versions!
