I’m a (lazy) oracle manager then i hope i could do with a sqllite database
Anyway, I got all I needed ! Thanks a lot
Edit : it worked well when I try it 2 days ago but touching the image restore it (obviously) to its normal state and the kobo firmware which display continuously the collection or the library by «*recent*» does not help.
It should indeed be great to add this to KoboUtilities with a menu «*set this image as screensaver*». Anyway, the idea is so simple, you’re a genius to had point it out.
