For me the final stage before mixing is to remove all the MIDI tracks. Audio tracks only, and only the tracks that I know I intend to use or are likely to use - so I strip out anything I think isn't going to be needed. This might act as a constraint, but some constraints can be very useful if they help remove indecision. At least I think they can :-)
Before I had two screens I normally had console view sitting in the dock occupying around a third of the screen height (pan knobs downwards if that makes sense). Now I use one screen for each. I don't like mixing without being able to see at least some tracks as I use clip colours to identify sections and seeing them is how I can be sure of where I am in the arrangement. The navigator kind of does the same thing and pre-dock I used it a lot.
Now I mix with tracks in top screen, console in bottom. I can work with just track view but don't like to. I can switch between console and track "mind states" without a problem and console view can show more tracks/busses than track view for a given screen size.
It might just be habit learned when DAWs barely existed of course, but I find console view very useful indeed for fader and pan riding and simply a logical way to do some things quickly and easily.
