I am seeking a software program to help me in reading large .pdf documents.
In my work it would be very helpful for me to be able to read through a large document and assign one or more categories to each page, then be able to sort this so that I can look at all the pages under any given tag.
So for example I might mark each page as "Client A" or "Client B" or "Client C" as well as "Urgent" or "Long-term" and then be able to sort the pages by any of these categories.
Does such a software application exist?
