Hi,

There is a single feature that would make Adobe Acrobat unbelievably useful: the ability to create tags and then filter by those tags. Here's why:

I'm a lawyer. We review discovery (i.e., evidence) in PDFs. I make portfolios to quickly scan through each document. What we want to do, however, is tag and filter them. I want to create a tag for "relevant," "irrelevant," "key document," or whatever. And once I've created a tag, to be able to single-click tag documents as I review.

Law firms pay billions of dollars to e-discovery companies for proprietary software that does this.

The power to do this is already in PDFs. You just need to add a "#relevant" tag that is inserted into the meta-data. Thus, you would tag 20 documents in a portfolio and then search the portfolio for #relevant and you'd get those 20 documents.

Every public defender office in the country would use this. And the applications beyond the legal world are huge. It is such a simple feature that it's shocking it doesn't already exist.

The key is that you need a panel where you can single-click tag or hot-key the tags so that a reviewer can move quickly, without having to open multiple windows.

Thanks!
