[Feature Request] Option for displaying buff timer on associated action button
For skills that cause an associated buff (eg: Slice and Dice, Blade Flurry), it would be great to have an option for it to display the duration of the buff on the action bar button in the same way that cooldowns are shown. The priority would be that if the option is enabled and the buff is active, then show the buff duration, otherwise show the cooldown if the skill has one (eg: Blade Flurry has both a buff and a cooldown, but the buff duration itself is more important information while it's up).
If it's too complex to make the action bar aware of the corresponding buff for the skill in that slot, would it be possible to have a configurable option for the buttons to watch for a specific spell ID as a buff to show the duration for (eg: bar 1, button 3, spell ID 12345).
I'm currently using a WeakAuras to achieve this, but it's a bit of a pain to configure and line it up to sit over the top of the action bar.
