Why are all property values lowercase in the segment filters?

To make sure filtering profile data when configuring segments is as easy and intuitive as possible all property values are normalized to lowercase when the data is indexed. This makes sure you don't have to select all (mixed-case) variants of a profile property value when configuring a filter; instead you select the normalized lowercase value without worrying about the exact spelling.

This doesn't mean however that the actual property values are lowercase.
