When converting a KFX to an Epub, most of the time the cover is marked correctly as the cover (as viewed in Calibre's editor), but sometimes there's a duplicate "cover" that's actually at the bottom of the file list. OK, fine: Publishers are, umm, technologically challenged and don't even handle this consistently in house.
That's only sometimes, though. Whether the table of contents will be "marked" as the table of contents appears to be completely random: I've done multiple KFX books from the same imprint of the same publisher, all released during the same month, and sometimes the table of contents is marked as a table of contents and sometimes it isn't -- regardless of what epub version it's converted to. This wasn't a problem with AZW or mobi inputs so far as I remember. But I'm not sure if this is:
A KFX Input thingy (bug, feature, you choose);
A general KFX thingy;
Random goofiness from the 'zon;
Publisher incompetence, especially when blindly creating e-book files from Adobe;
My computer getting drunk and just doing random stuff to annoy me;
More than one of the above.
Thoughts?
