Sorry, I guess I didn't explain what I wanted to do. The reason for this is because I want to make my game mobile friendly, which means it has to support multiple aspect ratios. After reading the supporting multiple screen manual, I've come to the conclusion to use Scale Outer Mode. This is the reason for my questions.
1: I want to create 2 windows to act as a template. For example, the main window will have a 4:3 aspect ratio, so all my important objects will be in there. The second window will have a 16:9 aspect ratio. With the second window I can organize to ensure that the player sees only what I want them to see.
2: Again only for reference purpose. I am worried that if it is at the edge, it might not display the objects outside the initial layout properly, since top and right left side will be outside the layout. Also, if I want to place two windows there, I will need to be able to move the initial window to place it properly in the second window.
Hopefully what I say makes sense.
