They're currently/still bugged. Sometimes they decide to update and sometimes they don't. They also like to leave people off and make you try to click the character model. In terms of customizability, they're pretty barebones. You can make them bigger and drag groups around your screen, but that's about it. Also, since I'm sure someone will come in and complain or cheer about it, there is no click to cast and no mouseover healing. Click the frame of the person you want to heal, cast your heal. Rinse and repeat.
