Possible UI enhancement - check the readiness / status of Jukeboxes in the user list

[IanVaughanRHD]

Once a Jukebox has been set up, it will appear in the list of Jukeboxes along with the device that was selected and also the playlist that was used. Whilst it is possible to go in and edit those values, it might well be that the device last used is now no longer active or available to play. If you start using that Jukebox, it will then give an error message, but perhaps this could be brought forward and the application check the status of any Jukeboxes in the list and give a visual cue if one or more are not ready to be used to bring the error state forward to the user's attention? This would likely be useful if an in use Jukebox suddenly stopped working (for example if the user whose Spotify account was in use, switched there playback to a different device to that set in the Jukebox properties)?
