I doubt we'll ever see this, but I would love for there to be a Schematic View tool for creating & managing our ootp universes. For those who are unfamiliar, it would look something like this:
We would be able to easily drag and drop boxes to form the framework and associations of our various leagues in much less time. There would be different colored boxes and/or different shaped objects. A Red Box signifies the head of a league. Then you drag and drop two green boxes under the red box to signify sub-leagues. Then you drag and drop yellow boxes under the green boxes which represent teams. Everything would be connected by lines with arrows directing the path you've created. It would end up looking like a big family tree!!
And you can double-click on any of the boxes you've installed into your universe and the proper settings would pop-up allowing really fast changes. I don't know about you, but I prefer to be able to see stuff like this rather than having to imagine it in my head.
