Icarus started as an design for a tweak by Devy Design originally named Kangaroo.
Icarus is a complete overhaul of iOS' multitasking gesture system. It replaces the traditional app switcher with a custom one, capable of much more than stock iOS. By using system gestures to smoothly integrate Icarus, using it should be second nature. Donations are greatly appreciated - MTAC - Devy Design
Why are some apps previews black when first launching the app and opening the switcher? - Icarus uses Apple's methods for grabbing the apps's snapshot. Since these aren't generated until the app is launched, it defaults to black. Caching for previously launched apps will be added as a work around.
Why does SpringBoard crash sometimes when killing all running apps? - A fix will be included when a better method is found.
