The functionality is different across the themes

There is a option in the Manifest theme that says play here. It actually works reasonbly.

However, that functionality is missing from the other themes (classic, contemporary). Please make the “play here” option work in all themes.

Secondly, the play back groups feature, in classic and contemporary themes, does not work. In my use case, I want to play to a chromecast and to the volumio device.

Thanks,
KP
