I would like to request the following feature:
Let’s say you have many rooms with speakers in each of these. You are currently playing music in one room, but are going to one of your other rooms. In this situation, you are currently able to continue listening to the same music in this new room, by holding down the play/pause button, and grouping with the other room, but since you have already left this other room, it would be nice if you could instead just transfer the music from the other room, to the new room, and not have it continue to also play in the first room.
I suggest implementing this by e.g. a double tap on the play/pause button, while holding down the button during the second tap. So if you just long press on this button, it groups with the previous speaker, but if you double tap + long press, it transfers music to this room (basically grouping with one of the rooms already playing, and when you release, removes all other speakers from this group)
I personally think this would be an amazing feature to have, making it easy to transfer music from one room to another, when moving around your house.
