Been using Calibre since I got my NC, and love it. I just wish it (or the NC) handled cover art a lot better. Calibre seems to create a jpg file in the same directory as the ebook for the cover, instead of using the on on page 1 of the ebook, most of the time. I get a lot of blank covers that do have cover art on page 1 on my NC.
I've tried to find solutions (save "epub as epub", and convert in Sigil -then in Calibre), but none have been successful.
Good call letting people know about Calibre though. It is very good.
