Adds a Friends Button to the topleft of chatbox with quick tooltip preview of who is online. Opens a friend list on click. (Displays only wow friends, not battle.net friends)
Download, unzip and put it into your /_classic_/Interface/AddOns/ directory.
If you want a quick tooltip preview even on retail, you can put addon to /_retail_/Interface/AddOns/, just rename addon folder from “ClassicFriendBtn” to “BfAFriendBtn”.
