Dual Monitor Support - Feature Request

I think it would be really useful if you could pick which windows you want to display where. Possibly options to make and save custom layouts would be really useful.
I have two monitors and wish to have one as a constant Full Screen Preview of the Grade so I can see the colour changes properly but I can't find an option to do this. I don't think it's possible to grade when looking at a 4 inch preview window.
