More advanced demo?

This looks a great project but the demo is very basic. Has anyone got a version that includes any of these:

1. Initialising from a saved state
2. Having input boxes in the blocks that can be saved to the output. Having data from the Right Panel saved to output.
3. Having the right panel be configured differently depending on each block clicked.
4. Loading blocks into the left panel from JSON rather than hardcoded into html.
5. Filtering in left panel working

I know these are all things that can all be achieved with some work - but its a lot of boilerplate for every new person to work on when its core to the simplest implementation.
