Don't know if it has already been said, but the Discord Action Bar support is bugged:
in the DiscordAction function, should replace:
a1 = ActionButton_GetPagedID(a1:GetParent())
a1 = a1:GetParent():GetActionID()
Because what we want is the action id, not the button id (they may be different in DAB).
It starts bugging if you have bars with more than 12 buttons, it even triggers cooldowns for wrong spells.
EDIT: great mod btw
I'd enjoy it even more if it supported total cooldown parsing on the tooltip, so that an UI reload doesn't reset the full time.
