I would find the exact opposite faster. Looking at something I'm used to looking at is easy, and it'll help muscle memory to be persistent. I don't have to decide I want to change, then wait while my hand triggers the popup, then parse the shapes.
That's not to say that the popup isn't a good idea, but the only benefit I see is I screen space.
