I am new to add-ons and I am looking for an add-on that will give me bars with the CD of trinkets and spells.  For example when a trinket like Darkmoon card: Greatness procs a bar will show up on my screen showing its CD. Also; when a spell is used and it has a Cd before it can be used again, a bar will show how much time is left until I can use the spell again.

Thank you for the help. 

Proc's are random so a CD timer is somewhat moot since it is not guaranteed to proc the instant the cooldown is done... CD's for trinkets that you manually pop you could just use the addon "cooldown" which will give you a numeric countdown on the cooldown of any ability, item, etc..

You can also try omniCC.

Natur enemy castbar does it. Just disable all the bars except the CD one
