Appearance
Applies to the book, the deck and the sign-in page alike.
The book
Which of the two views a page opens in. You can still swap with the toggle in the bar, or by pressing p.
Reflowed text searches, wraps to a phone and links onward; the scan is the printed page exactly as it is, colours and all.
Pace
How much new material the schedule hands you, and how hard it works to keep it.
What gets asked
The order new cards arrive in
The kinds of card
Switch a kind off and it leaves the queue, the forecast and every count on the Progress screen. Only this does the opposite — it switches everything else off, so you can spend a session on one kind.
Chapters
Narrowing to a chapter is the quickest way to spend a week on one system. It narrows the queue, the forecast and the drill list together.
Your progress lives in this browser
Nothing is sent anywhere — the schedule is stored on this device, under this address. A different browser, a different machine, or clearing site data all start from nothing, so save a copy before you need one.
