Open
Description
There's a general desire to be able to act on the system without always specifying which room to act on.
Eg, issue #16 - it would be nice for JoinGroup to be able to look up what room is currently the coordinator and default to that. It would not work in a scenario in which multiple groups are playing at the same time, but there's no way around that except to specify a room.
Functions like next, previous, and so on would also benefit from this feature.
