The most important thing about timlii was its ability for interactivity between different layers in one single dashboard which makes it very efficient tool when you have many dashboards running at same time. It's not as powerful or flexible than other tools like Tableau but I think this should change soon because there are some cool features coming up from their roadmap (I hope). We used timlili mostly for our internal analytics purposes so we were looking only into performance analysis part of business processes using multiple dimensions such as date range etc..
