Cuttab: Capture a Card, Question, or Pair от Mitologiya

Cuttab is a spaced-repetition (SRS) study app: flashcard decks, multiple-choice quizzes, matching exercises, and fill-in-the-blank texts.

This extension adds a "+ Cuttab" button whenever you select text on any site. One click turns that selection into:
- a front/back flashcard, in an existing or new deck
- a quiz question (you fill in the answers)
- a matching pair, in an existing or new matching exercise

Right-clicking a selection also works ("Add to Cuttab").
