[Q] Need a quick clarification on KNOX, AOSP and S-View topic

Hello all!

I just flashed the SM-N900W8 KitKat update through Odin, and I am still on Knox 0x0. I really want to try out CM11 and see how fast KitKat can fly on the Note 3!

I have gotten confused with the multiple threads for rooting and how to keep Knox 0x0, I'd like a bit of clarification. If I use CF-Root, can I keep 0x0?

Simply put, is it currently possible to flash CM11 on my SM-N900W8 and retain 0x0?

Finally, I have a genuine Samsung S-View cover. Is there some way to emulate the functions of the S-View case on AOSP?

Thanks!
