UI suggestions

Hi,

Great little device (the Puck)! Couple of UI suggestions for the editor:

1. Make it possible to load the app currently running on a connected device into the editor
   
2. Display the device name ( eg Puck.js xxxx) in the UI banner so you know which device you are connected to..
   
   

(would also be good to be able to permanently change the device name - but I suspect that's not possible)

cheers...
