Where does KOReader store extracted book covers?
I have an idea of applying these covers to cc.db so that Kindle can show books with covers in main menu.
I used sqlite on Kindle to replace an Entries called p_thumbnail with a path a random screenshot for specific book with:
Code
sqlite3
UPDATE Entries SET p_thumbnail='/mnt/us/screenshot_2020_02_11T02_29_37-0500.png' WHERE p_location='/mnt/us/documents/fb2 books/Юваль Харари - Sapiens.fb2.zip';
.quit
Have a look at the attached screenshot: the second book has a screenshot as a cover. It Works!

So if I can reach book covers extracted by KUAL, I can make a script to attach these covers in Kindle menu.

Alas, I believe those are in:

/mnt/us/koreader/settings/bookinfo_cache.sqlite3

And it's a pixmap in the device's native pixelformat (i.e., Y8 on Kindle), not a traditional image format.

(In this case, it's natively supported by PNG, though, so an encode would be somewhat trivial).

Given that KPVBooklet is severely hobbled on current FW versions, I wouldn't bother too much anyway.

just installed KOreader. Big Thanks to the developers! Works nice.

Just one question:

Is it possible to make KOreader my default reader?

So that every Document (epub, mobi, pdf) is shown in my "Kindle Library" (instead of the koreader file manager) and when i click on it, it starts with koreader?

@AverageDude: Technically, yes (that's KPVBooklet). Realistically, no, as that's been slightly to severely broken for quite a while on "newer" firmware versions, and it's unmaintained, which makes it effectively unsupported, since if you ever report an issue, my first answer is going to be: does it happen if you reboot the device and start KOReader with KUAL instead? .

Ah Thanks for the quick reply!

i am afraid i did not quite understand your question. I started KOReader with KUAL every time.

Is there any other option? It's not hard work to first look for kual and then start KOReader.. but it would be very convenient to "start reading" right away when i switch on my kindle. Is there any possibility to autostart it? Or to create some kind of shortcut on my dashboard?

Used to be:

https://github.com/koreader/kpvbooklet

But now it is broken on newer firmwares. So basically : don't use that & learn to live with starting Koreader from KUAL.
