Posted this on Uservoice, thought I'd make note of it here: http://bit.ly/aK21dQ
Sometimes I find myself wishing I could open multiple layouts. Perhaps I'm in my sermon prep layout and I want to spend a moment taking a closer look at Greek so I open my Greek layout then have to switch back to the Sermon layout when finished. I'd like a way to open that second layout in a floating window while leaving the first layout still open rather than having to switch entirely from one layout to another.
