Hide mixer channels

[cloudpilot73]

Would it be possible in future to be able to hide mixer channels and just have the bus channels visible and unhide them for minor tweaks hear and there. My reasoning behind it is to avoid endless scrolling left and right. I've tried just having the busses on one end and colour coding the sub channels, but it still feels messy and awkward. Just a little "hide / unhide channel" toggle will do.

Expanding/collapsing mixer groups would be a godsend!

Surely if Props can blindly remove features from the mixer, they are capable of adding new ones?
