Extend Flic Chromecast to Chromecast Audio and other Cast devices like Google Home
Be able to pause/play music on Chromecast Audio and even the Google Home and Google Home Mini (which will overcome the issue that Google Home Mini has no pause/play physical interface).

This works in the current version. The only problem is that when you are selecting wich google home mini to use you only see the product ID or something like that, instead of the name of the device. You can see what I mean by going to Tools > Chromecast. All of your google homes should be there.
