Adds a draggable, always-on-top overlay with global grading, flipping, audio and undo hotkeys, customizable styling, grading sounds, and an escalating Focus Dim system to keep reviews on track.
Displays customizable, color-coded overlays of remaining new, learning, and review card counts during reviews, with animated +1/-1 indicators and configurable position, font, and current-card highlighting.
Flashes a brief colored glow around the card after each answer to reflect the grade, with customizable colors, glow settings, grade mappings and per-deck toggles.
Colors Anki's answer buttons red, orange, green and blue for each rating, with a flash animation on click, working automatically across all card types with no configuration.
Adds countdown pressure bars with color warnings, shake and miss overlays, auto-flips cards on timeout, supports deck-specific limits, blur-to-reveal focus, and multilingual settings.
Displays Heisig or custom kanji keywords in pop-up overlays on hover and color-codes kanji according to whether they have been seen or are unknown.
