Hi ChuckC
Screensets can be really useful depending on your work flow. In their most simple use if you find yourself rearranging the layout of your workspace a lot chances are you'll find a screenset useful.
Having said that for just jumping from console view to track view the multidock is great, just pressing D will show or hide that.
One example where a screenset can come in handy for mixing is if you use a lot of busses. Set up the console view in one screenset with just tracks visible copy it to another screenset, hide all tracks and show only busses so you now have two screensets one console view track only, one console view busses only. Of course that can be mirrored in the track view as well.
Switch between them as required, very fast and easy to do.....
Here endeth the screenset sales pitch....
