Floating Interrupt Highlight

v1.3.0

New

• Almost-Ready Preview — while an enemy is casting an interruptible spell, the icon now appears greyed out during the last 1.5 seconds of your interrupt's cooldown and lights up in full color the moment it's ready. Enabled by default, can be turned off in options.
• Warlock support reworked — the addon now follows Command Demon, so it correctly shows Spell Lock or Axe Toss based on your current pet, and shows nothing when your pet has no interrupt. Re-detects automatically when you summon or swap pets.
• Empowered casts — enemy empowered spells are now tracked with a correct cast timer.
• /fih debug — new command that force-shows the icon and glow, so you can position and style it without needing a casting enemy.

Fixed

• The icon could appear late if your interrupt came off cooldown in the middle of an enemy cast — it now appears the instant your interrupt is ready.
• Disabling the addon now fully sticks; enemy casts can no longer make the icon reappear while disabled.
• The glow animation no longer restarts and stutters during long casts (e.g. when a cast gets pushed back).
• The cast timer no longer disappears when the glow animation is turned off — the two options are now independent.
• Fixed a potential error when reloading the UI while an enemy was casting.
• Switching to a profile with the addon disabled no longer turns it back on.
• The cooldown swipe is no longer stale at the moment the icon appears.

Changed

• Major performance rework: casts from units other than your target/focus are now filtered out before they ever reach the addon, and the addon does zero work while idle.
• Spell detection after talent or spec changes is now smoother (no icon flicker).
• Updated for patch 12.1.0.
