I am working on a layout for iOS devices and I want to zoom in on the layout so I can position things more to my liking. There used to be small "+" and "-" icons at the bottom of the layout and now they are gone. I can't figure out how to make them come back. Also, the View -> Zoom In and View -> Zoom Out are disabled.
Is there a magnifying glass tool or something?
How come I can zoom in out and out in other layouts but the iOS one seems locked?
