This is what many use Power Auras for. It is fully customizable.
Any comprehensive buffing addon can do it: Satrina Buff Frame, Elkano Buff Bars, etc. Also, Debuff Filter.
Timer addons can also do it: DoTimer, ForteXorcist.
Rogue specific addons can do it: Rogue Power Bars, Slice Commander.
Having tried all of these, I chose Power Auras in the end because it can do everything al the others can and it is only one (very popular) addon.
