DISCLAIMER: Android L by Nucleoid is the only (or one of the very few) that really swaps settings layout without repainting all dark holo apps and so avoiding messes and incompatibilities. For example white on white or horrible colour combinations. For now you just have to change to stock theme to add a new wifi connection or else it will force close. UPDATE: Cyanogen has found a fix and all roms will update soon and fix this small issue.
Android L theme by Nucleoid is designed to work on Cyanogen latest theme engine, it will change the look of your smartphone and will resemble the new style of the upcoming android version "L".
Android L by Nucleoid starts on its release by theming the main core components of your phone, its system and framework and will gradually transform into a full themed experience were we will update the number of elements by pushing frequent updates.
