As you begin to explore 6.0, you will notice that there are no longer Insights on the Cases screen. 

You might be wondering to yourself - where did the Insights go?

The answer is that the new Widgets which allow you to build both default and customized views for Cases and Alerts have been designed to replace the Insights. 

Information which previously would have been captured and displayed prominently using Insights, are now displayed using Insight Widgets and displayed in HTML format.
