Is there a way to mirror the control strip on the touch-bar to have the volume controls on the left instead of the right?
In order to change Touch Bar icons press commandspace and type keyboard then press enter. It will open to the Keyboard pane in System Preferences.
Then click the Customize Control Strip… button and from there and you can drag icons down or move down your mouse pointer to select and drag icons from or to elsewhere on the Touch Bar.
Note that if your Touch Bar is collapsed, touch the < on it to expand it before modifying it.
