Scrolling Combat Text Grayhoof

Fairly simple but very configurable mod that adds damage, heals, and events (dodge, parry, windfury, etc...) as scrolling text above your character model, much like what already happens above your target. This makes it so you do not have to watch (or use) your regular combat chat window and gives it a "Final Fantasy" feel.

Displays all of your class/spec's rotational abilities on a common time scale. This means that instead of seeing a regular percentage-based timer bar, EH shows you exactly what is happening in relation to everything else. The basic idea: An ability that lasts 12 seconds and has 6 seconds remaining shouldn't look exactly the same as one that lasts 5 minutes and has 2.5 minutes remaining.
