This is just a donation for PropEditor application.
By installing this application is a way to show some appreciation for my work.
The application PropEditor should be installed first: http://goo.gl/6QIJZa
Donation version is not actually an application is more like a key used by the PropEditor application to check the donation made.
By donating, the main application functionalities are not changed.
Thank you very much for your appreciation!
