Yes, that is the topic.
With your grade 2 (Android 9) is the screensaver option available? On my Poke 2 the screensaver option is not available in the KOReader menu. Neither on the APK of github nor on FDroid. I know the function from my Kindle.
Screenshot: Press and hold the title image and it zooms to full screen and then take a screenshot (tap left bottom and top right). I can also set the path to "/Pictures" and removed the date in "/frontend/ui/widget/screenshoter.lua" so that the file is always "/Pictures/SScover.png".
But I don't know the internal program structure well enough to do the following in an acceptable time: When loading a document, remember on which page to open, go to page 1 (title page), zoom in on the picture, take a screenshot (fixed filename, suppress message), jump to the target page. I would also need a new "class" screenshotcover to be able to take normal screenshots. And sure there is a way to do that invissible. That is more than very tricky for me.
I think it would be smart if KOReader had an adjustable action in the menu when loading documents. E.g. set a sleep timer or save the cover to a file.
