Interrupt Glow

Interrupt-ready = your button glows!

InterruptGlow makes your interrupt button light up only when it actually matters: your target or focus is casting something kickable and your interrupt is off cooldown. If it’s on cooldown, no glow—because false hype is cringe.

Also shows the remaining cooldown time.

Works with target + focus, most macros, all classes, and supports Blizzard Cooldown Manager.

Addon doesn't work? Try testing macro: "/iglow state" when target is casting something interruptible.

And send me addon's chat messages in comments.
