This addon shows both weapon bars and tracks durations of your active skills. Its main goal is to be as lightweight as possible and fine tune each tracked ability to show only most useful effects.
Features
1. Highlighted active skills and current weapon bar.
2. Instant swap animation. No more boring flipping icons.
3. Fine tuned abilities like Teleport Strike (show Minor Vulnerability applied by it), Focused Aim (Minor Fracture), Shadow Image (stop countdown after you port to your shade), etc.
4. Gamepad mode support.
5. High performance, which adds some limitations though (read below).
Missing features
1. This addon doesn't track ultimate duration. I'm still not sure if it's needed, and also showing both ultimates won't look neat due to their special button visuals, especially in gamepad mode.
2. The addon doesn't track your enemies debuffs, so if some abilities are purged or dodged, they will keep ticking on your bar. I'm not planning to change this behavior now, because I want to keep the addon as lightweight as possible.
If you want to move action bar, then I recommend using Azurah. There is no point to add this feature to the addon, because it will obviously conflict with other addons which allow to move UI elements. Note: Azurah re-enables weapon swap icon by default, so you will need to hide it in it's settings (Action Bar tab).
