Make Interface Display in Builder Collapsable

On a complex app, the interface display in the builder can become very long. I would like to be able to collapse areas as in an outline, being able to click [+] / [-] to collapse/expand each area to make it easier to see each section.

Very good idea, I would also like to be able to freeze top row

Good idea, I think it should also apply to the database display. On some larger apps (I will have over 60 objects when all is said and done), the list is very long! I would love to be able to organize objects manually into folders, and also more collapsing for pages in the interface. Not just the top level pages but also their sub pages.

I would also like this, in addition to making the objects groupable and collapseable.
