The ability to turn off embedded styles, landscape mode, calibre integration, pdf file support
KOReader is a document viewer primarily aimed at e-ink readers.
Main features
portable: runs on embedded devices (Cervantes, Kindle, Kobo, PocketBook, reMarkable), Android and Linux computers. Developers can run a KOReader emulator in Linux and MacOS.
multi-format documents: supports fixed page formats (PDF, DjVu, CBT, CBZ) and reflowable e-book formats (EPUB, FB2, Mobi, DOC, CHM, TXT). Scanned PDF/DjVu documents can also be reflowed with the built-in K2pdfopt library.
full-featured reading: multi-lingual user interface with a highly customizable reader view and many typesetting options. You can set arbitrary page margins, override line spacing and choose external fonts and styles. It has multi-lingual hyphenation dictionaries bundled into the application.
integrated with calibre (search metadata, receive ebooks wirelessly, browse library via OPDS), Evernote (export hightlights), Wallabag, Wikipedia, Google Translate and other content providers.
optimized for e-ink devices: custom UI without animation, with paginated menus, adjustable text contrast, and easy zoom to fit content or page in paged media.
extensible: via plugins
and much more: look up words with StarDict dictionaries / Wikipedia, add your own online OPDS catalogs and RSS feeds, share ebooks with other KOReader devices wirelessly, online over-the-air software updates, an FTP client, an SSH server,

v2020.07 KOReader 2020.07 "Tumbleweed"
It's been a busy month, so I'll get right to some of the highlights.
Ruby (furigana)
Ruby characters (also known as furigani) are now supported in the form of the <ruby> element, small typographic annotations to aid pronunciation (#6305).
Rotation handling
Usually I tend to emphasize user-visible changes, and in a way this one's both. Rotation was refactored (#6309), which immediately and easily allowed for better Android TV support (#6327).
The following screenshots showcase the new rotation handling on Chrome OS (running Android apps) and Android TV:
calibre
The calibre metadata search and calibre wireless connections were merged into a single plugin (#6177).
search metadata changes:
- search directly into calibre metadata files.
- search can be performed on more than one library (configurable from a menu)
- device scans now find all calibre libraries under a given root
- search options can be configured from a menu. (case sensitive, find by title, author and path)
- removed legacy global variables.
- option to search from the reader
- option to generate a cache of books for faster searches.
calibre wireless connection changes:
- keep track of books in a library (includes prunning books from calibre metadata if the file was deleted locally)
- remove files on device from calibre
- support password protected connections
- FM integration: if we're in the inbox dir it will be updated each time a book is added or deleted.
- disconnect when requested by calibre, available on newer calibre versions (+4.17)
- remove unused opcodes.
- better report of client name, version and device id
- free disk space checks for all calibre versions
- bump supported extensions to match what KOReader can handle. Users can override this with their own list of extensions (or from calibre, by configuring the wireless device).
