1) Please allow us (via checkboxes?) to select which parts of the collection data get exported (title, author, publisher, etc.) if "Bibliography only" is not selected.
2) Include more than just the standard bibliography fields. Include all the library fields (type, tags, rating, etc.) , so that we could export our entire library, for backup or other purposes.
3) Unless you're planning to do #2, "Bibliography only" should probably be renamed "Bibliography" because there isn't anything more than bibliographic info that gets exported if you turn that checkbox off; it's just in a different arrangement. In fact, the checkbox as it exists is kind of confusing. If it's turned off, isn't that just another format of export? So why isn't it one of the radio buttons? Call it, say, "Paragraph Style" or whatever you want. But it's essentially another bibliography style, just not one of the industry standards.
4) Allow comma-separated (*.csv) output so it can be read into Excel.
