does Xmultiwindow or Xhalofloatingwindow work on cynogemod 12.1?

I'm running cm 12.1 on my note 4 and Xhalofloatingwindow does not work right, It crashes the system ui. Xmultiwindow sorta works but the side bar will not slide close once it's been open. Only way to close it is to close all the windows.
