Pull request from jertux fork

Hi Benedikt,

Thank you for your email, and your Application !

We modify the same files, you will need to merge...

And you will have to select what you want to merge because some commits are maybe not useful:

* "Android 4.4 permission issue" --> you've already done this one
* "Change icon if node is clicked" --> maybe useless for most users : when icon is "checked" or "unchecked" type, it swap on clic... but as the file isn't modified, the change is lost when it is reopened

Cheers,
Jerem
