CiviCRM users rely daily on many of the "out-of-the-box" fields, like communication preferences and demographics, to send targeted email communications and create basic reports. While these fields are essential in many smart and basic groups, they have historically taken up prime real estate in the contact record view.
The new "Collapse Comms and Demographics" extension cleans this up by displaying information graphically within collapsible field sets.
Our brains prefer this type of display, since we can process graphics much more quickly than seeing the same information as text. Neuroscientists from MIT have found that the human brain can process entire images in as little as 13 milliseconds.
With the extension, you're basically getting what you need to know about your contacts, nothing more and nothing less.
