Just wondering if there is a way, or could possibly ever be a way, to select a quantity of books (eg. 10 or so) and bulk change the stylesheet, or embed fonts. I just hope it's not already a thing and I've just missed it all this time!
Although I did a search and didn't find anything.
A large portion of my ebooks were put into Calibre quite a while ago, when I still had my old Hipstreet M701. On this ereader, I didn't need to embed the fonts as I now do with my Kobo. Plus it could also display in color, which tells you another little tweak I did in some books...
At the moment, to read them 'properly' I need to open them one by one, embed the fonts, make sure it doesn't have problems (as occasionally a font will fail to embed, and then I have to find out why and change/correct) and then resend it to my Kobo Aura.
It's not a big thing by any means, and if it never becomes possible that's perfectly fine, just a random question that came to mind.
