Full LED control. I was so very disappointed in stock android when I saw what the LED can REALLY do (you can pick almost any color under the sun for battery alerts or notifications that you can set up for per app basis)
AOSB in black (EXACTLY the same as PAC in black)
All CM11 features.
You select how many steps there are in the volume control
Good battery life(Can play a lot of games throughout school and it'll be at around 4% when I get home from school)
Slim Recent Apps
Split view(Even though I don't know what you'd use it for on a phone)
Full nav. bar/ring editing support.
No Paranoid Android type control of the UI, which I was kind of hoping for, just a type of it through a preinstalled Xposed app
Outdated Xposed and Kernel tweaker, but since their modified they can't be updated from GPlay store. I ended up uninstalling them from system then reinstalled them from GPlay store, but was kind of irritating that they aren't newest versions.
Poor built in kernel. If you want kernel features at all, you'd have to find a good CAF kernel out there (I'm running Chaos Kernel v11.1)
Long hold back to kill app doesn't seem to work
No ability to have the menu button EVER show up unless you manually add it to nav bar, but then the buttons look weird since it makes all the buttons closer and it plain looks weird for it not to stick to the right or left side.
Doesn't get very dark(I also noticed this in stock, but was hoping that there was some change here, but no luck)
Google Camera's HDR+ makes the app crash (Google camera also doesn't automatically install over built in camera app)
All in all I love this rom, but it is a little rough around the edges. NOTE: I don't know if it's just me or what, but I had problems with supersu, but I'm not sure if it was the rom or me just accidentally messing up stuff
