EventHorizon_Infall

Event Horizon Infall takes cooldowns and auras of abilities from your default Cooldown Manager and displays them as timeline bars. Every bar shares the same time scale, so you can see when things come back, when they overlap, and how they relate to each other. 

This image shows a moonkin's Moonfire debuff bar configured in both Infall (top) and the default cooldown manager (bottom) as a bar. The difference is that the default Blizzard bar shows 100% to 0% no matter the duration. The Infall frame is configured to show the next 16 seconds on a relative time scale:

Most Infall setups will be configured to show many rotational cooldown bars, relative to each other. 
The white "now" line splits past and future. Bars slide from right to left. If two cooldowns end at the same time, they'll line up. All bars move at the relative time set by the future timescale:

The original is EventHorizon by Brusalk and EventHorizon Continued by Calen. Infall is a rewrite for Midnight.
Some functionality did not make it. Some are still being iterated on.
