I ended up purchasing the Professional edition. In that edition, the menu > Views > Open Additional Window option is enabled. While I have not verified if this feature is available in the Standard edition, my guess is it is not.
I'm deciding between the Standard and Professional editions. I want to have Device View in window 1 and then to observe changes I make to the device network in 3D View in window 2 (because the preview window is very small). I only have one monitor.
The Pro version says it provides "Multimonitor Support". However, I have a feeling that really means "Multi-Window Support".
Do I need the Pro version to have multiple windows on a single display?
