Hi Tommy,
I've just tried "opf2mobi" for the first time, and I have a question. Apologies if this has been asked before, but I really don't want to read all 50+ pages of this thread

.
The end result is excellent, but I've found that it doesn't appear to use the items in the "Guide" section of my OPF file, which work fine with Mobi Creator. I don't get a cover image unless I use the "--coverimage" option, and the "Table of Contents" link in the resulting file takes me to the first page of the file, rather than the "TOC" link defined in the "Guide" section of the file.
