Hey this is GREAT ! ( I've been waiting for this for about 18 months)

All seems to work pretty smoothly on my system.

Definitely would be nice to see the zone Names instead of ip addresses ( especially as you can't assign static IP to sonos zoneplayers)

Also there seems to be no option for 'All tracks' after you have browsed to an album - it seems you have to add to the queue one by one - or have I missed something....?

Overall though - good effort!
