(As an alternative/complement to the earlier suggestion about putting zones into standby automatically…)
Could we have a single button which powers down all devices (well, all those devices that support the protocol anyway). “ALL ZONES OFF” would sit very logically and cleanly alongside “PAUSE ALL ZONES”.
Currently it’s four clicks per zone (select speaker icon, select power icon, push standby button, deselect subwindow) which for 10 zones is quite a pain.
While we are at, why hide the standby button in a sub-window and require the extra click on the power switch icon anyway? Why not just include that little extra bit of the window pane when we choose the speaker icon? Design seems overcomplex here.
