the appearance panel has lots of scrolling going on

## Use Case

In the left hand Appearance Panel, when channel settings are open there is lots of up/down scrolling to keep changing things.
Q: is this concern for moving between channels themselves? or for moving between channels and the other ui features above the channels?

## Solution

unknown. one possibility is to at least make the Channels section a separate dockable widget so that it is scrolled independently of the other appearance settings.
