Tested,
first file HAS blank page at the end, second doesn't. Landscape works as expected if set from device, in the rotated page the behavior is a little bit odd (when viewing in landscape it actually displays portrait
) IMHO but it's me, I'm sure someone'd find it useful
Also, the cover doesn't seem to be displayed twice, don't know why.
For the Personal tag I'm fighting with MOBI header hexadecimals and Amazon's hypersecret metadata - with no luck, until then.
Hope night brings counsel...
