Several options:
- Master PDF Editor, version 4 is free (and in AUR);
- PDF Arranger, good for bulk edits;
- jPdfTweak, a veritable swiss knife of PDF editing;
- jPDFBookmarks, the best for editing bookmarks;
- Briss, for bulk cutting PDFs;
- Krop, also for cutting, but less flexible.
I love copyq so much. It's definitely one of the apps I first install in a new deployment. When I hear of the troubles some people go through for not having a clipboard manager, I just smh and think, 'copyq'.
