highlighting locked pdf desperately needed for scientists
I am a scientist. In my field we process and review many pdf documents and need to take notes on these documents to perform proper experiments.Often we are combining knowledge from several pdf sources by writing notes on the sides. I am requesting you make personal commenting and highlighting available on locked pdf documents. It is very annoying to have to print and jot notes and underline text of importance. Often our documents are hundreds of pages long and this is not practical. Find a way to allow these features in a locked pdf document. Perhaps this could be done in some sort of over layer of the document rather than editing the actual information itself.

This is not only needed for scientists. For valid IP protection reasons, HBR began locking pdf's of articles for for paid subscriptions. This means I can no longer highlight the electronic versions of articles. Now I must print them and highlight the paper copy. Would be very helpful to have the requested capability.
