Hi all, I am looking for a good app for my iPad for reading and annotating scnientific papers. It should at least have the following properties: 1. dropbox integration or another possibility to exchange files easily with my desktop (also for folders with many files so one by one transfering is not desirable) 2. possibility to mark text by freehand (rather than selecting the text you will mark - too much of a hassle) 3. possibility to easily set color and thickness of pen and marker before (not after) writing/marking I have tried UPad but it failed for number 1. I have also tried goodreader but it failed for number 2 and 3. Does anyone know the right application for me? Thank you very much!
