Deckle v0.5.2

Deckle 0.5.2

New

• Pick the font for your paper's title. Choose Blackletter (the old look), Serif or Sans, or use any .ttf font file of your own. Find it under The paper → Title font on the Daily tab. It changes the title on the cover and the PDF edition. Inside the book, your Kindle's own font still applies.

Fixed

• The Upgrades screen no longer offers books it can't upgrade. Older MOBI books that Deckle can't rebuild are now left alone, and the screen says how many.

Pre-alpha. The Kobo, PocketBook and reMarkable support is still untried on real devices.

macOS: signed and notarized by Apple.
Windows: code-signed by Casa Vargas LLC.
Requires Kindle Previewer 4 (free, from Amazon).

Deckle v0.5.0

Deckle 0.5.0

Your morning paper can now go beyond the Kindle, and Deckle can now fix up the books already on your Kindle.

Your paper, on more devices

• Send it to an iPad or Boox through iCloud Drive or Dropbox.
• Send it to a reMarkable.
• Send it to a Kobo or PocketBook.
• Look back at any past paper: browse, search, and send an old one to your Kindle again.
• The Daily tab is easier to find your way around.

Your books

• Upgrade the books already on your Kindle (the DRM-free ones) so they read like store books. Your original copy is kept, and you can undo it.
• See everything on your Kindle: what you've read, what you haven't.
• Free up space, and back up and restore your books and highlights.
• The Books tab now shows your whole library, with search and series.
• Send PDFs, Word documents and text files.
• Combine several files into one book.
• Export the words you looked up to Anki.

Pre-alpha. The Kobo, PocketBook and reMarkable support is new and hasn't been tried on real devices yet.
