Steps to reproduce the bug

Filter and sort icons near the search field look very similar and could be confused, for instance by older users.

Also, in my opinion, the filter icon does not really represent it's usage (filtering through address books)

Expected behavior

Filter icon is more meaningful and different from sort icon. For instance an icon that represent an address book, like this open source one:

Actual behavior
