TellMeWhen provides a flexible system of icons for displaying vital information (and only vital information) about cooldowns, buffs, debuffs, and reactive abilities... always in a consistent place on your screen.

Some examples of things you can do with TellMeWhen:

• Display an icon when a clearcasting buff procs
  
• Display an icon when an ability or boost trinket is finished cooling down and is ready to use
  
• A death knight could have icons appear to show when Freezing Fog procs, when Rune Strike is usable, and when Horn of Winter drops and needs to be refreshed
  
• A mage could have a Polymorph icon appear when the mob they've set to focus becomes unsheeped
  
• A rogue could monitor their own stack of Deadly Poison on a mob, and have icons appear when they need to reapply poisons to their weapons
  

You choose which spells, abilities, items, buffs, and debuffs TellMeWhen shows. Cooldown icons can be shown when an ability/item is either usable or is unusable. Buff/debuff icons can be shown when the buff/debuff is either present or is absent. Icons can be set to only show in combat. Icons can show timers on cooldowns and (de)buffs. Compatible with OmniCC for text display of time remaining.

Instructions

General options are available in the Blizzard interface options menu. You can type "/tellmewhen" or "/tmw" to lock/unlock the addon. To configure individual icons, right click them when unlocked. When you're finished and ready to play, enable the icons by locking the addon.

For buffs and debuffs not in your spellbook, TellMeWhen will at first show a pocketwatch icon to indicate that it is waiting to learn the texture for the buff/debuff. The icon will have the correct texture after you encounter the buff/debuff while playing.

Remember that buffs and debuffs sometimes have different names than the items and abilities that provide them. For example, the Death Knight ability Icy Touch applies a DoT called Frost Fever.

Features planned for future versions

• Settings for icon opacity
  
• Allow single icons to check multiple buffs/debuffs
  
• Support for dragging spells/items onto icons
