Get Developer Options old version APK for Android
Opcje skrót developer
Shortcut (and widget) to developer options settings.
If it is frustrating for you to look through the whole settings menu for developer options (well hidden in Android 4.2), before and after each development session, this is the solution.
Since version 1.1.5 you can get developer options even quicker - using Google Now gesture.
