This app caused me a lot of trouble. I tried to save some PDFs and they were impossible to open in any reader. I opened them with Notepad++ and they were now HTML files. Also, there is security issue of giving full access to your PDF downloads away. Sometimes financial institutions generate PDFs with account and identiy information; this app by default doesn't ask you if you want to give it to them, it just automatically does so.

I like the concept and hope to download a future iteration. Just some feedback.
