Parfait que l'appli ait été mise à jour. C'est une vrai bonne idée. J'avais le projet de m'atteler à réparer l'originale, mais, je ne m'y suis jamais mis ^^ comme beaucoup d'autres choses.
Regarding the comment by "Miguel Garza". Your bad rating is not justified. Amazon killer does not do anything extraordinary in itself, it is not what it is meant for. All it does is extracting the unique book ID from Amazon and finding it in an **existing** DB of books stocks. You can use only 3 french websites because librarians in France gathered to build their own database of book stores stocks. The database itself has nothing to do with this plugin. Now you can bad rate plugins without understanding them but you could also start a movement in your own country to encourage bookstores owners to gather together and setup the kind of infrastructure and DB like placedeslibraires.fr did !
I really want this to work--remember BookBurro?--but it only shows three bookstore websites and they are all only French language. There should be a better explanation of where this extension works, in the name of the extension and/or in the description.
