-Customizable-Fully customizable dashboards for any type of data source (ease)-Easy to understand reports are generated with minimum effort.-Ability to create/import own widgets from other libraries like OpenX, JavaScript etc.. I would be very happy if they have some modules available where you can import Excel files or JSONs which we could use in our Dashboard easily without doing much coding work! Nothing at all!! It's completely free as well so no complaints here :) Have used it internally when working closely related projects over multiple years now along side many clients who also liked its features best was generating easy understandable visualizations & graphics using their charts library called "Klip".
