The dashboard could be improved and include additional features. 

In terms of data modeling, it could be simplified. Sometimes, it seems complicated. Also, the response time for data set refreshes could be faster to enhance the user experience.

When looking at web-based BI or cloud-based BI vendors, there should be abilities for power users to build deep analysis. If they are not data science tools, they are not for power users. 

Some of the advanced analytics need work, and I believe there's an opportunity to improve or simplify the integration with data power users and data science users.
