All the titles of an author are grouped and separated by letters (which you can access directly). When you click on an author's name, all their books appear (which can be ordered in different ways) and if they belong to a series, this is also separated in case you want to access only the books in the series.

A long press on any book (no matter if it is ordered by date, genre, series, author...) gives you the option to access all the books of the author or series (and to open with any reading program installed: PBReader (epub 3), PBReader (epub 2), KOReader and CoolReader).

The renderer of Koreader IMHO is the best and You have pop up notes and great choices about font sharpening and line spacing and many other things. Of course Koreader is not so well integrated with the rest of the Kobo or Pocketbook system (statistics ecc.)

I agree. But margins and line spacing (even if you only have 3 visible options) you can modify them to the millimetre and set them to your liking (with KOReader's own text editor you can do it from the e-reader itself).

I find much of this thread very confusing. Are we talking EPUB vs KEPUB (or even Kobo) or has it turned into a completely differnt topic about a different brand reader (that does have its own forum section)?
Sorry to be a bit grumpy but I am genuinely interested in and am trying to understand the actual differences between EPUB/KEPUB and I get lost here!
