Currently you can mark an item and see details/drill-down on a separate adjoining visualization on the same tab.
But if you were to have a summarized/executive tab with say trends ... and you would like to see details/drill down on a new/separate tab that is not possible right now. That is, one cannot click on a bar in a bar graph and see a details visualization on a new tab (which competing softwares offer).
Note: This is only possible on a graphical table (through actions on click) ... a similar option should be available on all charts.
