OmniBar is easily customizable, and has a rich feature set.

Customizable Cooldowns

Open the options panel to easily select which cooldowns you wish to track:

Multiple Bars

Create as many bars are you want!

Automatically Hide Icons

When a cooldown is used, its icon will be added to the bar. After it's complete, it will be hidden automatically. This allows more cooldowns to be tracked, while avoiding awkward gaps between bars.

Show Unused Icons

Check this option if you prefer the icons to always remain visible. The Unused Icon Transparency slider will adjust the transparency of the unused icons. Check As Enemies Appear to only show unused icons for arena opponents or enemies you target while in combat.

Track Multiple Players

If another player is detected using the same ability, a duplicate icon will be created and tracked separately.

Profiles

Create custom profiles with dual specialization support.

Cooldown Count

Allow Blizzard and other addons to display countdown text on the icons.

Glow Icons

A glow animation will be displayed around an icon when it is activated.

Note: This functionality does NOT work in the backport.

Visual Tweaks

You can configure various visual tweaks such as size, border, glow, transparency, columns, and padding. OmniBar also includes Masque support.
