The attached example demonstrates how you can display different views of content based on the context of a dragged block. Using jQuery’s sortable functionality, we can drag blocks from one list to another. These lists then define the contexts in which we display a specific content via CSS.

I gather this approach wouldn’t be ideal when each node has a lot of content and blocks aren’t moved frequently; An ajax approach might be better in that scenario. Trickier modifications can be applied to this basic principle, wherein you display and hide sub-nodes selectively within each block (e.g. hiding a column in a table, non-summary paragraphs, etc).
