Interrupt bar (originally coded by Kollektiv) with several abilities/cd's added.
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.
For those who prefer curse and/or curse client:
Interrupts-only version here:
Type "/ib" for options -> now option to modify the number of columns.
Type "/ib columns #" with "#" replaced with a number then type '/console reloadui' to update the addon.
