Just dropping in here to say a huge thank you for this plugin. I don't have enough technical knowledge to understand most of what is discussed in the thread but suffice to say, I installed it yesterday and it is working beautifully. I have been fighting with ADE for years, it constantly says my books are missing despite being clearly in the library it uses, and i have to redownload, etc. It loses my credentials often and I have to re-authorize, etc. NO more. I used to buy a lot of my books from Google books but had stopped due to the ADE hassle.
