Here’s a sweet way to display properties. Basically, I had a bunch of generic properties that I was using shorthand notation for, and one that was a read-only property which served as an aggregate of a few other properties. I couldn’t shortcut it, but the implementation of it was trivial, so I hid it inside a region whose name looked exactly like a shorthand property. Tough to explain, but easy to understand:

Collapsed Property

Expanded Property
