We've said it before and we will say it again but XDA Recognized Developer rovo89's Xposed Framework (thread) is a great development, which now works with KitKat! This framework allows you to pick and choose the customizations you want on your Android device. If someone has taken the time to write a Module, or if you take the time to do so yourself you can get any feature you want from just about any ROM.

In this episode of XDA Xposed Tuesday, XDA Developer TV Producer TK reviews XHaloFloatingWindow. XDA Senior Member zst123 created this Xposed Module to allow you to get the Paranoid Android Halo multitasking feature on any device. TK shows off the module, its use, functionality and talks about his thoughts of the application. So check out this app review.
