Pdfsam 2.1.0e now adds a new feature to modify the PDF document information.
it also adds the possibility to rotate the pdf.

as usual to find in my overlay

it still has a small bug that the thumbnail generator for the visual plugins sometimes crashes.
I am working on getting the other render added to the source packages so you can chose witch on to use.
