Default stock features on CM11??

Hi all,
I'm new to this forum.
I've ordered my G2 which is expected to come next week.
I see that LG G2 stock has lot of good features but teams like Cynogenmod keep up with the speed of Google releasing latest version of Android. I was wondering if anyone has taken Cynogenmod and added features from stock rom to it.
If not, how diffcult is that? Is it as easy as getting those apk and installing or they need compiling build with specific options or specific kernal features to get them working.
