Categorize I'm looking for some help in finding an app for my ipad that would allow me to do the following: - Sort and view pdf files that I've put in certain categories. I'm in sales and I have one page pdf's of cases that I would like to be able to tag to the client, the type of opportunity, and the month the decision is going to be made. So I could look at all of the cases that are coming up September, 2011; or I could look at all the cases that are pending with Client A; or I could combine categories to look at all Client A cases that are coming up for bid September 2011. I would imagine there are apps like this that help people sort photos or data. - It would also be ideal to be able to post notes on each pdf file - I need this app to have some easy way to import these files, ideally through e-mail - I'd also like to be able to just search for my files.
