Objects and Pages as Modules vs Templates

Templates are great to get started or see how something works but you can't import them into an existing app. For those of us who have built out extensive apps with more complicated Objects and Pages, we would like to be able to use these in our other apps without having to reprogram them each time. We need a way to export specific Objects and Pages (a Module) and re-import them into another app. This then not only saves time and allows us to expand the body of work we can produce, but allows us to share modules with others and can also be the building block of a marketplace for ready made modules that you can snap into your app.
