Hi, I want to post some news about the progress in the work on the plugin.
The following points seem remarkable to me:
- the dependency on Ruby was completely removed
- the work is done completely in the background
- the work is integrated with Calibre's job system
- the only remaining problem is that Pdftk does not provide any progress hints, so the progress display is somewhat rudimentary
The changes are actually not reflected on my web page, but I plan to do this soon.
