Bartender3 is an Ace2 AddOn to provide more flexibility and functionality to the Action Buttons. It is NOT based on Bartender2, but a total rewrite. Although the functionality is basically the same, Bartender3 was explicitly designed for WoW 2.0

The current version of Bartender3 supports nearly all Features BT2 offered, plus some more, which include:

   - Full style control ( Alpha / Scale / Padding )
   - Split up Bars into Rows
   - Set the number of buttons per bar ( only 1 - 12 supported, for short bars )
   - Dynamic Page Swapping for Stances ( on all Bars, by default enabled on Bar1 )
   - Dynamic Page Swapping on Modifier Down ( Shift / Ctrl / Alt )
   - Custom Styles included: Zoomed Buttons ( Hide Border from BT2 ), Dreamlayout
   - Integrated RedRange and full support for Cooldown Count ( for example with OmniCC by Tuller )
   - Self Casting using a modifier key, or Right Click on the button
