chromecast: start playback on last player
The chromecast destination has to be selected each time the cast is started. I mostly use the same device for playback, so an option to auto-connect to the last used device would be a great help, especially when using a widget to start playback.
Everything related to the Chromecast is handled by the Google Play Services via their Chromecast button
Sorry but this button cannot be displayed on a widget and once disconnected from the Chromecast you will have to open the app and connect again

At least one other app has an option to wait for the last connected device and connect to it, so I assumed it is possible.
If starting a radio station from a start screen shortcut, would that not open the app again?
