FEATURE: show summary comparison of scenarios in index page

When running multiple scenarios with different inputs, it would be very nice to have way to see the comparison tables on the index page. Currently one needs to open each scenario in a separate tab/window to compare the (small) table at the top of the page. Having this on the index page would make it greatly easier to gain an overview of how different scenarios compare to each other.

The table could be collapsable, and the individual detail pages should remain as they are.
