add CM Development Shortcuts to AOSP with Xposed?

I have an android device running AOSP 4.4.4 and I want to add CM's "App Development Shortcut" feature to it.
If you don't know what that is, when you hold down on an app in the recents screen, there is an option to force close it.
Unfortunately I can't find the CM11 source anywhere.
Can anyone help me?
