Anki decks

apkg

An Anki deck opens as its cards: a grid of flashcards, each drawn with the deck's own templates and styling, with its pictures loaded as the card comes into view. Click a card to bring it forward; the arrow keys, or a swipe, turn to the next.

An .apkg is a zip with a SQLite database inside, so it can also be browsed as a folder.

Next: flame graphs.
