OK. Another test for PW users.
Second file have one page rotated to check double-horizontal pages.
Everything work correctly? (Personal tag is still here. I dont have idea how remove it - Messing with headers dont had any effect. I'm open for suggestions.)
No doubled pages? (Not counting first - Cover.)
And most important: No empty page on end in Portrait mode?
(Please check both files.)
There should be one page blank in second file. Page right before rotated page. But only
in landscape mode.
Developing something for PW without PW to test it is "fun".
