I spend a lot of time using pdf’s at work as well and I’ve often yearned for something that uses vim keyboard commands and allows some keyboard based tagging and also search functionality. I explored writing something, but my understanding is that muPDF is proprietary and not suitable for commercial use in many cases.

When I was researching building a third party pdf reader with super specialized functions, I found that pdf.js might be good alternative that could be used commercially.
