I love the design of this wonderful forum (forum.xda-developers.com) and so I decided to create a theme for CM11 or AOSP Theme Engine.
I do not know whether you ponrav this idea, so this theme is not so much change. Look of your application, I almost did not change, there is a leash small changes. The main changes relate to the notification bar and system settings. I also included some of the icons and bootanimations of Android L.
If I see that my brainchild you like, I will be happy to supplement this topic and other applications.
Specifically for users of this forum, I post this theme for free.
But if you like my idea, you can support me and buy this theme in Google Play for a small price.
