Thank you for this
excellent new feature
I had the luck to open a commercial book which had all the requisites and discovered a new footnotes display exactly like with a paper book (and more because you can still go to the note folder). Well, I am no too late since this feature was added to Koreader in October 2019...
I checked the difference between the code I used for ePub3 footnotes and this one. The only difference was the presence of a "
ntb" class in the
aside element (missing in my code).
This is mine but of course YMMV
Code:
.ntb {
margin: 0% 0% 1% 5%;
font-size: 0.85em;
line-height: 130%;
font-style: normal;
font-weight: normal;
text-align: justify;
text-indent: 0%;
text-rendering: optimizeSpeed;
}
It's surprising, but once you know it, it's just a trifle to add it and enjoy this feature.
Lots of ebook readers still do not have this feature.

and congratulations to the developers!
