As I said before, Calibre is a very useful program that I will continue to use (even though it doesn't work properly on my mac, and tends to corrupt the prs-505 sometimes), but this is a different program with a different focus.
Feel free to write you own program, I'm just curious as to what features you think are missing.
calibre does gather all your books into a single place (a database in versions <= 0.4.83 and a user specified folder in higher versions). Not sure what you mean by indexing by format. You can filter the list of books by format, what else do you want to do?
