The beginning has been amazing - install the script go to Google download the app and go in any bookshop and add pictures with QR
But after it changed all , the app no longer work like it should and the support is now really down-
So I removed all , over 2000 books and removed this script- Is a pittya s the idea has been amazing and I am sure that this would be a bestseller, but.....
The author has an amazing customer support, and the plugin works like a charm. Nice selection of extra extensions and theme packs if you need to build a more flexible book list of your own. I can only recommend this plugin :)
