I just recieved a brand new Kobo and don’t know what to do with KoReader.
What does KoReader more then the Kobo Aura H2O reader?

In screenshots of KoReader I see only scientific publications and the technical possibileties of KoReader like font size etc. Is the KoReader not suitable for ebooks?
On my Android smartphone I have installed the Aldiko reader. With Aldiko I can sort on autor or title.
I can see my books on shelfs or in a list. I can find books selecting from a list with the tags.

In Calibre I also can assign books to series and fill in or download summaries and other stuff.
Which of these things appear after copying to the KoReader?
