Great Hack Mr Geek, thank you!
i just installed 1.2 and noticed two things you may can think about in future versions.
1. All my seperate add ons were gone. It would be fine if the could stay after an update or include all add ons in your version
2. Also the amazon-ID was gone. maybe you could create a separate field so it will not be overwritten during update.
Thank you for your work!
