CM11 HeadsUP Notification for calls topic

hi guys i had maclaw's cyanogenmod 11 rom for a while then i changed to android andi slimkat and one of the things i enjoyed about it was the headsup mode for calls. it works like this : when u get a new call and the screen is on (u are doing something on ur phone) the call doesnt block the whole screen, instead there is a popup that u can choose to put away. i wanted to know is there something like that in thisCM11 that i missed? coz im lookin for reasons to go back to it
thx anyway
