Not sure wat this does but ill post wat i found on it
Features
Boss mods for all raid bosses
Colored raid warnings!
Bars can be enlarged when they are about to expire
Some boss mods have very advanced features like the Loatheb healer monitor which allows you to setup a heal rotation and see the cooldowns of all healers
Synchronization system for accurate timers
No dependencies, no embedded libraries, 100% stand-alone
Modular design - all boss mods are plugins and can be exchanged, removed or updated separately
Load on demand - boss mods and the GUI are separate AddOns and they will be loaded when they are needed, e.g. the GUI uses no memory if you don't open it
Efficient code: low memory and CPU usage
Special effects like the screen flash and the screen shake effect to draw your attention on critical events - for example DBM will warn you when Thaddius changes your polarity
Bars can change their color over time and flash before they expire
Many bar designs to choose from, all designes are are customizable: you can change the color, size, icon position etc.
Option to create custom timers, so-called "Pizza Timers" for your pizza or whatever you prefer to eat while raiding
Powerful object-oriented API - you can use it to write your own boss mods!
