MikScrollingBattleText (MSBT) Mikord

Designed to be an extremely lightweight, efficient, and highly configurable mod that makes it easier to see combat information by scrolling the information on the screen in separate, dynamically creatable scroll areas. It is a replacement for Blizzard's Floating Combat Text and Damage output.

Enhances the default WoW scrolling combat text.

sct 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.
WoWInterface, SCT-Damage

WitchHunt Ammo

Spell alert mod. Will notify you of spells being used by players around you. It will put the notification in your scrolling combat text.
Curse, WoWInterface
