Copperhead seems to be great project however, from my user point of view, i’m not sure it is what i really expect.
I care about privacy and security, but I pay even more attention to functionality.
In other words, for casual use, i am more expecting a rom like Cyanogenmod with permissions management (privacy guard), easy customization* (tiles, menu bar, styles), and some smart improvements into defaut apps, etc
*without having to install Xposed and GravityBox.
