What can I do ?

Hey,

I am wondering if I am not going to ask some stupid questions and the answers will be : RTFM !
But anyway,

• Is there a light and battery event ? Like the mag one. I was wondering if I could trigger functions based on a light event, for instance, without having to use setInterval().
  
• Can I open an (android) app with the puck ? Using the button (or anything else)
  
• Do you think it will be possible to control spotify (as an example) on the a phone ? Button to open Spotify, magnetometer to control the volume, etc...
  
  

That's it i guess,
Thanks all (especially Gordon !)
