The “starter” dimension and metrics that Google Analytics now groups into five categories can be helpful when you’re defining your custom advanced segments. Many of the parameters commonly used in advanced segments, such as country value, are easily accessible through this new interface enhancement.
At the same time, keep in mind that these represent only a subset of the dimensions and metrics available, all of which are still accessible in the Conditions panel – as two examples, the important but often misunderstood Page dimension as well as the Event dimension, which you could use to create an advanced segment for visitors who clicked on Live Chat.
