Add a separate Contacts app or Contacts button for the PC version of Mail. It's hard to modify contacts from the PC version of Mail. It's annoying that I have to log in to the web version just to access the Contacts button in the browser. The older mail programs were easier to use and were more efficient. Some people may want to import and export Contacts from other apps. They may want to create labels. Apply this to all desktop versions (PC, Apple, Linux).
