This addon will automatically select a power when clicking on orbs. This is mainly intended for leveling alts, there are no configuration options and power selection is not really optimized (there are 800 or so powers total, including for those specializations that I do not play). I do believe the priority list is reasonable enough.
It does not know about all the powers, wowhead list in incomplete. If such power is encountered, you will have to pick it manually. Leave a comment with power id (printed in chat) if you want it to be added.
Known issues:
- Selection dialog does not close if you click an orb while in combat. Press Esc or select a power to close it.
