Schwarzschild is a buff/debuff/cooldown mod inspired by WoW's EventHorizon. It tracks all the important buffs, debuffs, and cooldowns for your character, and displays them in a single unified location, sorted according to when you'll have to pay attention to them.
Once you've installed Schwarzschild, type "/sc" ingame to open the config. It's not the cleanest configuration around. That'll be improved.
Doesn't yet support cooldowns, nor is there a way to move the window. Work in progress.
