An absolutely fantastic piece of libre software for reading ebooks.

I have it installed on my Kobo.

The top features for me:

Night mode. White text on a black background for reading at night. Amazingly you don't get this on default OS for the Kobo.
Wallabag plugin. You can download all your articles from Wallabag as epubs to read.
OPDS catalog plugin. You can connect to a remote OPDS catalog and download books from there. I connect it to my Calibre-Web instance.
Highlights. I use this a lot. Nothing too fancy but it does the job. It's quite nice the way it handles when a highlights spans multiple pages. I use KoHighlights to get the highlights on to my computer for processing.
Book Map is also nice.
