Love them, but don't use them. We should be able to tell the Icon what it's cooldown is,

E.g. give us a
/set cooldown 30

We use that one time in the macro and the icon on our hotbar will show the CD for 30 seconds and move down to 0 and be grayed out (not disabled) until it counts down to 0.

That would make my day, please add something like this SE.

I have a stun macro I like to use but don't because I can't see the cooldown of it on the hotbar and I don't like relying on /echo to tell me it's off cooldown
