I run a dual screen setup with all of my panels (Layers, Materials, Scenes etc) on my 2nd monitor, Now that I'm using Enscape they get in the way of the Enscape window so I've found a way to have 2 different layouts within SketchUp, lets call them profiles.
When I'm building I use my 'Full' profile with all my toolbars and panels on both screens then when I get to the point where I'm ready to start knocking out renders I switch to my 'Skinny' profile where I have just the necessary toolbars/panels on the primary monitor thus leaving the 2nd one free for Enscape.
It involves copying and inserting chunks of the Windows Registry for which I've written batch files so ..... I'm somewhat reluctant to post my process here as whilst I'm OK(ish) with potentially screwing up my own setup I'm reluctant to help other screw theirs. 
Is anyone interested in me posting what/where/how to do it or am I inviting a world of pain on myself and anyone stupid enough to think I know what I'm doing?
