It'd be helpful if there was a visual display on the side when selecting a document, so that I could see what I'm looking at and have the ability to rename it without completely opening it.

A good program (and nice people) A good program, a bit too comprehensive for me (in some ways), and a few (to me) important features were missing. After my trial period, I was accidentally invoiced for a full year, the support department solved that nicely.
