Awesome addon! Fading textures are great, but I only use glowing buttons.

Could you add the proc timers as a text on top of the glowing buttons (as an option)?

Hi and thank you for your feedback.

It's hard to tell how the number will be interpreted. Usually, numbers on action buttons indicate the countdown until next time the action is usable. In other words, it tells for how long it is on cooldown. The timer effect that this addon computes does pretty much the opposite: it tells for how long the action is off cooldown.

Also, it doesn't seem like it, but having a clean text over action buttons is a difficult task. Whether it is about the font face, font size or text position, there are so many things that can go wrong.

Maybe a solution would be to mask the glowing effect with a clock-like indicator, like this:

I'm not sure if this is technically possible, but that would be the best of both worlds, I think.

Hmm, "wrongly interpreting the number as a cooldown" would be a user problem I think. :)
But I see the technical difficulties. And it could collide with actual cooldown text displays. So the clock mask idea seems good to me.

I do really like numbers tho, more precise. Much easier for me to tell whether I can delay by another GCD or not than with the clock mask. On the other hand, I guess with most abilities you don't usually delay proc usage until the last opportunity.
