## Formats

- EPUB, MOBI, AZW, AZW3, KF8, PRC, FB2, FB2.ZIP, CBZ, PDF, TXT and Markdown.
- Reflowable books render through foliate-js in a WebView; PDF pages through PDFium.
- TXT and Markdown are converted to a single HTML document and read like any other book.
- Files opened from other apps, and folders attached through the system file picker.

## Library

- Scans chosen folders for books and keeps covers, titles, authors and progress.
- Grid, list, condensed and cover views.
- Grouping by author, series, genre, tag, keyword, language, publisher and publication date.
- Sorting by title, author, series, number in series, filename, size, date, page count and extension.
- Recent, favourites, read and unread shelves, and shelves of the reader's own tags.
- Search across the library; per-book search inside the open book.
- Book actions: open with, send, delete, add to or remove from the library, reset progress,
  mark as read or unread, file info.

## Reading

- Paged and vertical scrolling, one column or two, left-to-right or right-to-left.
- Page animation, fullscreen, screen-rotation lock.
- Table of contents, go to page over a grid of page previews, and progress by page or percentage.
- PDF: pinch zoom, page fitting, and the reading theme carried onto the page in night mode.

## Themes and typography

- Reading themes are the reader's own list: what is on it, what each is coloured, in what
  order it sits, and which of them the settings offer at a tap.
- Themes are added, recoloured, reordered by dragging, hidden without being deleted, and
  restored to the built-in set.
- A theme is edited over a live page, set in the book's own font, size and spacing, with the
  WCAG contrast of ink against paper shown in the title bar.
- Colours are chosen from ready-made papers and inks, by hex, or by RGB slider.
- Aged-paper texture, drawn by the browser in whatever colour the theme is.
- White backgrounds in illustrations can be multiplied into the page, so a drawing sits on
  the same sheet as the words instead of standing as a bright card on a tinted page.
- Bundled font families, font size, line spacing, page padding and text alignment.
- Hyphenation through the browser, Hyphenopoly or hyphen, with the languages chosen per shelf
  and the book's own language honoured or overridden.
- User CSS, applied to every book or only where the book's own styling is set aside.
- Find and replace rules applied to the text of reflowable books as sections load.

## Notes and bookmarks

- Highlights, underlines and strikethroughs in a choice of colours, kept per book.
- Bookmarks, each keeping the text it was made on.
- Copy, translate and search the selection.

## Reading aloud

- Text to speech with a choice of engine, voice and speed.
- A media session, so the notification, the lock screen and headset buttons drive it.
- Reading follows the voice: the paragraph being spoken is marked and the page turns itself.

## Metadata

- Title, author, series, genre, keywords, annotation, ISBN, publisher and publication date.
- Covers taken from the book's own images, from a file or from a link.
- Saving writes the fields into the book file itself: EPUB, FB2 and PDF for the fields,
  EPUB and FB2 for the cover.

## Elsewhere on the device

- Home-screen widgets: one book opened where reading stopped, and a shelf of recent books,
  favourites or a tag.
- A Wear OS companion showing what is being read, and driving the voice from the wrist:
  play and pause, skip, stop, and open the last book on the phone.

## Data

- Backup exports and imports the library, its metadata and the settings.
- Light, dark and e-ink app themes, and the interface language.
