Tired of hovering over your target or your party members to see what their class is? Well, Trav's Unit Frame Extensions adds class icons to the Blizzard Unit Frames so you can see their class at a glance! It also adds level information to party member frames, can make health bars colored, can hide or show the resting and in-combat indicators, and do more! Check the README for full info.
You can configure which frames will be modified by clicking the class icon added to the player frame, or by using the command "/tufe".
