[Android Themes] EnricoD:
​

This is a guide to show hidden android 4.3 features like OP.APP and Latin Ime Debug Settings (there's themes inside!! :D )... on developer options

If You want to add this to Your ROM or try make for stock Odex follow these guidelines using Apktool and Notepad++ (There's a plenty of guides on XDA :P):

1) Install framework-res from the ROM

2) Decompile Settings.apk from the ROM

3) Navigate to /res/xml and find/open development_prefs.xml in Notepad++

4) Put GREEN lines at the end of the file to show like this:
