Vertical Real Estate

RX has an option to “not” show the L&R channels separately. When appropriate, it gives the user twice the vertical real estate. Can SL6 do that? If not, maybe a future version?

In SL you can solo one channel in the Channels panel (then you will only see and hear that channel), but still edit multiple channels at once as long as multiple channels are active (highlighted) in the Channels panel.
