I currently have a 13inch MBP connected to an external monitor. I was wondering if it is possible to 'freeze' the desktop on the 13inch (acting as the secondary display in this setup with the 24inch as the main). so even if i swipe to another desktop or use an app in full screen i can still have the 13inch display the same desktop so i can keep static apps that stay open always available through the secondary screen regardless what the main screen is doing?
