For the Ipad, the epub books are displayed well, but the sorting the books into different folders once downloaded just keeps crashing. I cant create a new folder. Every time I pick a parent directory to put the new folder in it closes. Ive been using Calibre to load the books into the device, but you have to chose each book individually. Theres no "Download All" option. Calibre is a great program, and Id like to see a better inferface between them. But until the create a new folder problem is fixed, Im stuck with one.
