Please keep on playing, and writing down on a paper your ideas/questions/suggestions. But keep in mind that you might have to redo your stuff in our new beta version (since we haven't added any migration code in this early beta phase)!!
Another note on your popup idea. You could indeed - when you click on a camera icon - show a popup with the camera video footage (as we will explain later!!!), but I wanted originally to go one step further: I'm also developing a node-red-contrib-ui-camera-viewer node (with ptz control and so on ...), to simplify displaying camera footage in the Node-RED dashboard. So I wanted to show that same widget in a popup. However unfortunately that seems not to be possible 
, as you can read here. Case closed...
