Dominos_BuffTimes shows buff/debuff times (for spells that you cast) on action buttons as a cooldown (in addition to coloring the borders of the buttons). When used with OmniCC, this should show the countdown until a buff/debuff expires as a number on the button.
Dominos_BuffTimes was originally born as modification of Dominos_Buff (found with Dominos). Despite the name, it does not require Dominos to function, nor is it affiliated with Dominos.
What's new
It is now possible to show stacks of a buff/debuff in the bottom left corner of the button. This is a global-only option (not spell specific) and can be enabled in the configuration menu tick box labelled "Show Count".
Configuration
Default behaviour is outlined below. It is possible to configure the behaviour of certain buffs and debuffs via command-line (using /bufftimes) and interface options (under Interface->Addons->Dominos_BuffTimes).
Focus Macros
Where a button has a macro on it with a name containing " Focus" (that is "Focus" with a space in front of it, like "Banish Focus") the button will show buff/debuff times for the focus target.
Ignore spells
Spells can be configured to not show timers at all (for when seeing the spell cooldown is preferable - border coloring is still used). Default ignored spells are Judgement of Light and Mortal Strike.
Your buffs
By default, buffs will show times regardless of the original caster. Buffs can be configured to only show times if you casted the buff (for HoTs, etc.). Default buffs in this list are Renew.
Any debuffs
By default, debuffs will only show times if you casted the debuff. Debuffs can be configured to show times regardless of the original caster (for Banish, etc.). Default debuffs is this list are Banish, Fear.
Self-only buffs
These buffs will show a timer for buffs on you, regardless of who is targeted. It also overrides the actual cooldown, so for short cooldown abilities, you will see a green border and the time left on the button. When the buff expires, the green border will disappear and the normal cooldown will appear. This is configurable and there are defaults provided.
Spell Translations
This allows you to configure other spells that should trigger the timer on your buttons. For example, a warlock may want to translate "intimidating shout" into their "fear". This would appear in the Translations tab as "Fear -> Intimidating Shout". With this added, you would see the cooldown timer if the target had fear or intimidating shout active.
Override spells
These spells will show the timer if the spell is active even if the spell's cooldown is greater than the time left on the buff/debuff.
