I really like what safari has done with its devtools for the style editor.

Right-click inspect element selects the element you want to modify. Then change CSS properties in a GUI editor. Only problem is persistence.

I love designing and tweaking with devtools iteratively.

A lot of things are done in editors because it gives you a lot of control of logic. Designing assets in visual language like flash makes a lot of sense.

Unity has the same idea. Create your assets visually and assign behaviors to it via code. Their GUI/code fusion is pretty cool.

Writing a public var in a class exposes it in GUI and makes it bindable to other things via click and drag.
