Changed Flashcards so that every deck is studied with spaced repetition. Study, beside a deck's name and on each deck's row, opens the session of what is due today plus the day's new cards, and each answer sets when that card comes back. The Simple study setting is gone: the decks that used it now keep a schedule too, and nobody's progress changed.
Flashcards, Quiz and Cram are now under Practice on the deck's page. They never change your study schedule.
A finished Study session says when the next card is due and offers to go through the cards you missed. The Start again button is gone from that summary, because rating the same cards twice in a day pushed them further out than they should have gone.
The first intervals after a new card is learned now match Anki's FSRS scheduling exactly.
