The World of Warcraft casting bar has no settings you can configure The eCastingBar add-on to World of Warcraft is an great, and good looking, add-on that allows you to replace your casting bar with one that you can configure. It provides you with a user-friendly options panel and it allows you to resize, move, and restyle the casting bar in World of Warcraft.

When you first enable the eCastingBar, you will see four frames hovering about: the Mirror Bar Outline, the eCasting Bar Outline, the Target Bar Outline, and the Focus Bar Outline. Each frame allow you to move the bars and place them wher you would like.

The Mirror bar is used for monitoring your breath and exhaustion levels, the casting bar is used for everything else such as casting spells. The Target and Focus bars display the spells cast by your opponents.

You can open the options panel with the slash command "/ecastingbar" or "/ecb". Once you open the options panel, you can configure *all* of the settings for the eCastingBar. Once you get the bars positioned where you like them, you'll probably want to turn on "Hide Outline" for each bar.
