I deal with dozens of PDFs a day, most of them encrypted. Decrypting and re-encrypting every single one of them would be a lot of lost time. Besides, I don't get your reply, at all. Every single thing Evernote does already exists with other software, but Evernote represents a simple, intuitive interface for aggregating it all. Isn't that the point? To save time and make working more efficient? When competitors offer this feature and Evernote doesn't, it seems to me like it's just willing ignorance of a certain portion of users, letting them leave to the competitor.
