Leap 42.3/Gnome:
pdfshuffler is installed on my system from the standard openSUSE-Leap-42.3-Oss repo.
It works fine when the script somewhat cumbersome is started first and then add the wanted pdf file to it.
But using Nautilus, pdfshuffler isn’t found among the available applications on right-click pdf “Open with” menu (like i.e Evince).
I wonder why it isn’t integrated this way default, and next what is the easiest way (gui) to fix it?
Thank you, the first option worked.
I found pdfshuffler first time after that among <View all application>, selected it, and next time it was remembered as the last used app on top of the list. Next, started Evince from “open with”, and lastly after that found pdfshuffler also with “open with” (if that was interpreteable).
