Im working thru tutorial number 2. I drug scene one/used the arrows to clear the canvas to start on scene 2. I'm not really a fan of how the camera angle default zooms in while writing everything, I prefer it shows full screen. I set the camera angle on scene 1 to go full screen, and when I tried to do the same thing on scene 2 it now shows scene 1 pulled up and out of sight since the camera position is now full screen on scene 2. I've tried using undo keys, and also highlighting/resetting the camera angle to go back to what I had for scene 1, but it seems like its stuck.
