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. 

You can also try omniCC.

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