I'm using MC now for managing my digital books. My collection includes both permanent books and temporary library books.This adds up to a large and "dynamic" library, but with MC I'm able to cut down the clutter and manage them effectively. Keyword seach seems to be the most important took for browsing through the library, both using the "keyword" field and the "description" field. With these and other custom fields I can find any book in my library, no matter how obscure.
What I can't do as easily, is find the book I was reading yesterday.
"Recently Played" smartlist would be the obvious tool to find something that you just looked at, but MC doesn't currelty count plays for documents, or plays for sending to external programs. With my digital books I am always using MC to launch the books in an external reader, so I'm doubly out of luck.
Is there any method that would count when a document is played, or sent to an external player? In both cases a book is not "played" like a movie or audio track, all the way through, so I don't think it would be the same sort of event that a "play" is. But being able to search by when you last looked at a document would be an important tool for finding the darn thing, IMO.
FWIW, when I send docs to external player, it is to Acrobat for PDF files, OO for doc files, and Calibre e-viewer for everything else. The calibre suite, although well-intentioned, is a mess, I'm sorry.
