It would be useful to see a second column in the Auto-Layout box of the Inspector, with the names of any named constraints. At the moment its not possible to tell if a constraint has been named without double-clicking the constraint and opening it in the Inspector. It would be faster and more intuitive to see the constraint names in the initial Auto-Layout Inspector view. When playing with the constraints and laying out a UI, I often delete and add constraints, naming some but I cant see at a glance which still have a name.
