[ ] optionally reduce the size of generated PDFs by scaling bitmaps
[ ] get rid of UnoConv / Libreoffice for as many mime-types as possible as it is quite slow
[x] optionally save the generated PDF directly to a location in the cloud
this can be done by implementing a proper right-sight-bar tab
the side-bar tab (details view) could also be used to change preferences (overlay or not) for the current PDF generation
it could also contain a "please do this in the background" check-box
[x] converting large directories takes too much time. We should at least optionally move the PDF generation to the cron-jobs and just notify the user when its ready. The notification can contain the download-link.
