If you open the inspector Option+I you can TAB to show the track visibility for the the Lower Mixer and show or hide those as you wish. OR. click on the Show/Hide MixConsole Toolbar, click on the Set Channel Type Filter where you can Show/Hide the type of track you want to see.
For routing I just setup a key command to open the channel editor which gives me that
Left/Right sorting of track positions, aint gonna happen I dont think. Have to do that on the channels on the track area to do that.
F3 is a quick fix to your issue as you get the full mixer on your screen, one key push. Resize it down to where it still shows what you need and voila
