Bartender4

Here is a brief introduction on how to configure the action bar addon Bartender4. This addon can be configured in many different ways and should allow you to save a lot of space on your screen.

You can find the Bartender4 addon on Curse.com, Wowinterface.com, and other locations. Bartender4 is not the only bar mod you can use - Macaroon, Dominos, and many others will achieve mostly the same functionality. For PvP, all your needs should be met with any big name bar mod.
