Just another quick one. I found out that you can copy/paste camera's from one project to another. Just show the camera in the view you are in, select it and press +. Switch over to the other project and in Ribbon > Modify > Paste Aligned select Current View (when you are in a 2D-view).

Comes in handy when you are working two options on a project and are using two separate files. (Yes, I could have used the options-tools, but the difference between the two versions was just too big and too involved.)
