Floating Interrupt Highlight

A floating icon that displays your interrupt ability and highlights with a glow animation when your target — or your focus target, if you have one — is casting an interruptible spell.

Features

• Floating interrupt icon — Automatically detects your class/spec interrupt spell and displays it as a movable icon
• Glow highlight — Proc-style glow animation plays when your target begins an interruptible cast (can be toggled off in settings)
• Cast timer — Color-coded countdown timer on the overlay (red → yellow → white) shows remaining cast time (can be hidden in settings)
• Smart cooldown awareness — While your interrupt is on cooldown the icon stays hidden; it lights up the instant your interrupt is ready
• Almost-ready preview — During the last moments of your interrupt's cooldown the icon shows up greyed out, then fills with color the moment you can kick — so the cue never catches you off guard (can be toggled off in settings)
• All cast types — Tracks regular casts, channels, and empowered casts
• Focus target tracking — If you have a focus target, the addon watches your focus instead of your current target — set focus on the priority kick mob and keep fighting whatever you like. Can be turned off with the "Ignore Focus Target" setting
• Cooldown swipe — Optional cooldown sweep animation on the icon after using your interrupt
• Masque support — Fully compatible with Masque for icon skinning
• Friendly unit filtering — The icon only appears for hostile units, never for friendly casts
• Drag to position — Unlock the frame to freely drag it anywhere on screen; lock it to hide until needed
• Profile support — Per-character profiles by default, with full AceDB support for copying and switching

How It Works

When unlocked, the icon is always visible so you can position it where you want.

When locked, the icon is completely hidden until the unit you're tracking begins casting an interruptible spell. If your interrupt is on cooldown, the icon stays hidden — no point showing what you can't use. As the cooldown runs out, the icon fades in greyed out and colors in the instant your interrupt is ready.

Focus target: if you set a focus, the addon tracks your focus exclusively — your current target's casts are ignored until you clear the focus. This lets you assign yourself kick duty on one enemy while attacking another. The moment you clear the focus, tracking snaps back to your target (even mid-cast). Prefer the old behavior? Enable Ignore Focus Target in the settings and the addon will always watch your current target.

The addon automatically detects which interrupt spell you have based on your class and spec, and re-detects it when you change talents or specialization. Warlock pet interrupts are fully supported: the icon follows your current pet (Spell Lock or Axe Toss) and shows nothing if your active pet has no interrupt.
