Spell Buff Timers

Spell Buff Timers shows how long your buffs have left directly on the action bar button of the spell that created them. It works for any class.

Instead of checking the buff icons in the corner of the screen, you can see at a glance when to re-cast a Seal, Blessing, Mark of the Wild, Arcane Intellect or any other self-buff.

Features
- Cooldown sweep and countdown on every action button whose icon matches an active buff on you
- Readable text: 1h, 59m or plain seconds, with the unit letter small at the bottom right of the number, inside the button
- White text until 2 seconds are left, then yellow fading to red, with a smooth decimal countdown (1.99, 1.98 ... 0.00)
- Works in combat: the add-on learns each buff's duration out of combat and starts the timer from your own cast during a fight
- Supports the default Blizzard bars and ElvUI

Commands
/sbt - diagnostics
/sbt max N - ignore buffs longer than N seconds
/sbt min N - ignore buffs shorter than N seconds
/sbt size N - timer font size (0 = automatic)
/sbt reset - clear learned durations

Limitations
- Only buffs on you are tracked, not buffs you put on other players
- In combat, the add-on needs to have seen a buff once out of combat to know its duration
