Weakauras 2 is the backbone of this interface, if you want to use this UI there is no simple way to use your own weakauras settings.If you use 'Weakauras 2' already, but also want to use this UI: Nice when you're setting up from scratch. Pro tip: Type / and copy this command: run for i = 1,120 do PickupAction(i) ClearCursor() end.Hover over any button and hit the key you want to bind. The thing is built with existing AddOns only, however some minor tweaks are applied in the code to make the addons match the visual style or behave more convenient. It aims to be fairly conventional but still offer all tools needed for high end play, such as buff/debuff trackers, cooldown counters, threat driven nameplates, improved tooltips, better resource tracking and decent raid frames.
This interface is somewhat inspired by the 'Guild Wars 2' UI and is designed with any class/spec in mind. FYI: I've recently 'kinda' re-made this with up-to-date mods.
