Are there any good ebook metadata editors out there? I've got a metric assload of ebooks, and the metadata is mostly crap, and the filename formatting is all over the place. I'm looking for something that can do for my ebooks what mp3/Tag Studio did for my music, and that can handle multiple formats (epub, mobi, lit, and pdf at least). ie, an all-in-one bulk editor and file renaming tool.I know Calibre can do these things, but it seems to be in several steps in different parts of the program, and I loathe Calibre in any case. Please tell me there's a better option.
