I'm trying to find a clear answer as to what is the expected behavior when assigning an application the mission control desktop option of "none"? What I'm noticing is it acts as if it was assigned to what ever desktop I was on when opening the Application. Does that sound right?
Yes, but you can also have different windows from the same application on different desktops. Put differently, you can more or less use the application independently on each desktop. Does that make sense?
