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.
0.8: Fix packaging error.
0.7: Fixed a bug or two. Added compatibility for the breaking changes announced for 1.10.
0.6: Fix some error spam.
0.5: Fix errors in 1.6.
0.4: Fixed loading bug, now sets position properly and doesn't spam you with errors.
0.3: Fix a merge issue that caused those two items to not show up properly.
0.2: Added movement options. Added a new checkbox, "group buff", for buffs/debuffs that only one member in the group needs to (or, sometimes, can) provide at once.
