In the Zone Grouping modal window, it would be great if each zone still had a checkbox so you could specifically choose which zones you no longer want music playing in. This feature existed in previous Roon versions but seems to have been removed with the addition of the Zones right-side vertical blade UI.
Scenario: you start music in the ‘living room’ zone, then add the ‘office’ zone into a group, and after some time decide you want the same music to continue playing but only in the office.
With the latest Roon version, the ‘Zone Grouping’ window won’t let me simply uncheck the living room zone. Instead, I have to ungroup (leaving music in LR) and then transfer to the office zone.
