Latest CyanogenMod 11 nightlies now come with floating notifications, protected apps, more
The most notable new feature is the so-called "Heads Up" notification mode. It is nothing else than floating notifications – whenever you receive a new push notification, it will be displayed in a window on top of whatever you are doing on your device. You can not only see the notification, but expand it and interact with it. Don't worry, this floating notifications mode also comes with a handy "Do Not Disturb" feature, which allows you to select what apps it shouldn't interrupt.
Interestingly, the developer claims that the code for said functionality has been "buried" into the source code of Google's mobile OS for quite some time. Does this mean that future iterations of Android might officially come with similar functionality?
Another new trait of CM 11 is the Google Now integration within the user interface. The default CyanogenMod launcher, Trebuchet, now takes you to Google Now whenever you swipe to its leftmost position. Neat, right?
Protected apps is yet another new CyanogenMod feature. It is, in fact, a brand new functionality of the previously-existing Hidden Apps feature, which allows you to hide apps on the system level and protect them with a custom Pattern Lock. This renders them invisible from all launchers and prevents unauthorized users from uninstalling them or clearing their data. You can still access the hidden ones via the Recent section in your multitasking menu.
Another change that most CM 11 users might have noticed is the overhauled Settings menu. For example, the Interface section has been split into several categories – Status Bar, Notification Drawer, and Gestures. According to Cyanogen, the changes within it should allow users to get to their "favorite CM features more easily".
