I use the little green button with my workflow heavily. I'd like to be able to add a monitor for displaying web pages that i'm not directly working on. For example, if i'm working on web dev, I want to be able to switch between screens on my laptop while not effecting the display on the monitor.
Currently, with the monitor being an extension of my laptop display, if i switch between windows with the green button feature on, the monitor also switches and goes black.
