A basic mod that tracks enemy abilities: typically interrupts.

Left Click the bar to move it. Go to the options to lock the bar. You can also hide buttons until they're active. /ib for options. In the options you can make it so the bar only shows when an ability is fired.

Type "/ib" for options there is now option to modify the number of columns.

Type "/ib columns #" with "#" replaced with a number then type '/console reloadui' to update the addon. == This can be used to create a variety of shapes (and use of decimals can yield interesting and occasionally preferable displays).

The addon can be dragged when in the "unlocked" status by clicking+dragging on the top left of the addon.

Flexible and additional updates incoming in the next few days. Works with current version of WoW and is currently fully functional. Addon layout is basic but a "pretty" version is a possibility in the future.

This addon is featured in several PvP videos and has generated a total of about 30,000 hits. I'm now bringing it to curse so that it is more widely available. Thanks to all for your support, and I will continue to maintain this addon for as long as I can.

Be aware that the code can be edited (fairly easily, I might add) so that additional spells are on the list. Tutorials exist online for how to do this.
