please add support of opening pdf portfolio for reading and annotations.
the bullpen app is not particularly useful for all kinds of professionals. i am a Lawyer, who relies on extensive use of pdf portfolios. currently i have to use foxit pdf for the portfolio files or adobe reader. however, i am in luv with drawboard due to the features provided by it. the only difficulty is that to use drawboard i have to extract the files out of the pdf and use.
