====== About the script ======
  * Purpose : This script will dim all other stuff if you open a folder
  * Author : [[https://plus.google.com/+LukasMorawietz|LM13]]
  * Current Version : 2.3
  * Link : https://plus.google.com/115366157037831519359/posts/24AHYbCWrXn
  * Video : https://plus.google.com/115366157037831519359/posts/3ZY4BWnZbmp
  * Download avialable! (Check repository)

====== Changelog ====== 
  * Version 2.0 (28/5/2014): initial release in wiki
  * Version 2.1 (18/7/2014): auto create item
  * Version 2.2 (16/11/2014): bugfix, apk version contains UI
  * Version 2.3 (4/12/2014): bugfix

====== How to use the script ======
  * in the folder: set the dim script to paused and resumed event
  * set up configuration if you don't like the standard values 
  * Note: this is the manual way, you won't need the setup script for this way

Or: Simply load the apk in that folder

====== Issues and hints ======
  * the orientation fix may interfere with your desktop boundings, so keep it off unless you need it
  * Note: The setup Script won't work outside of the APK

//please report all bugs in the g+ community//
