pdf-notes for iPad
On 7th July, free version of pdf-notes for iPad 2.7.0 became Ready For Sale. I am sorry but the 2.7.0 paid version was dropped because two significant bugs were found, crashes while exporting an image or uploading books to Dropbox.
Paid version at http://itunes.apple.com/app/id417200844
Free version at http://itunes.apple.com/app/id391487223
This 2.7.0 supports exporting multiple books at once and book-cache management feature to pre-open multiple books or remove old caches.
