I'd love to see an app tackle this. Some projects require different components. For example, if I'm planning an event, I may want a document that contains ideas, links, pictures (more like notes); a task section; a calendar section. Most apps have these in views that go across the board. I have to do planning on separate apps to get the types of data and views I'm looking for. It'd be nice to be able to put together modules with different data sets or content and visualize it under one project or board.
