Hi Avi,
A simple one for me is to include current selections in a text box that then has a trigger to open a selections box when clicked on. It saves space overall, but also clearly shows what is selected on that tab.
Other things are:
Search object - always a stand out functionality
Images - Being able to dynamically show and also filter images is pretty cool
PCA chart - Have only tested it but this example is a good way of showing correlation correlations dimensions in your data.
Mike.
