Related question: doing the above had some pain points so I wrote an app to give me the ability to give files and directories human readable names. Read, annotate, and bookmark the pdf within the app. Then be able to search across the whole library on annotations and keywords which would open the pdf to the page and paragraph the annotation referenced. The big thing it does is answer the question: I have read something that I need right now, but where in this huge pile of paper (or directory) is it?
I have gotten the app to the MVP stage, is there any other functionality that would be useful, and would anyone else find this useful?
