Study screen now matches the provided mockup's layout: a "Current
Deck" panel with a circular mastery-progress ring, and a "Spaced
Repetition" panel (New/Due/Learning/Review counts, streak, daily
goal) on either side of the card. Kept the app's real global sidebar
rather than the mockup's own nav, per direction.
Mastery/Streak/Daily Goal weren't tracked anywhere, so this adds real
backend support rather than showing fabricated numbers:
- Mastered = graduated to review state AND FSRS stability >= 21 days
(FlashcardScheduleStore.MasteryStabilityDaysThreshold), stricter
than the plain Review-state count
- CurrentStreakDays = consecutive UTC days with a review, computed
from review-log timestamps in the new pure FlashcardScheduling
.ComputeStreakDays (unit tested, habit-streak semantics: doesn't
reset to 0 the instant a new day starts before today's first review)
- DailyGoal/ReviewsToday reuse the account's existing ReviewsPerDay
setting rather than inventing a new one
Also removes the exit "X" button in favor of the same Escape/pause
menu the question-player flow uses (main.gd's shared app_menu, with
an "Exit Study Session" action), and adds a new circular_progress.gd
reusable ring control plus a real "Options" menu (bury/suspend the
current card) wired to schedule endpoints that had no UI before.
refresh_theme_controls() colored the divider and the ANSWER/KEY
TAKEAWAY captions, but it only ran on an actual theme toggle - never
at initial build. Confirmed live: the divider was invisible (default
white on a white card) and the captions rendered as plain body text
instead of the intended accent color until you toggled dark mode
once. Call refresh_theme_controls() once at the end of _build() so
the correct colors apply immediately, which also fixes the same
latent gap in empty_label's color.
Study card: label the answer and "key takeaway" as distinct sections
with a real visible divider (previously an all-but-invisible
HSeparator) instead of one undifferentiated block of text. Also fixes
a real gap where a cloze card's extra field was silently dropped,
since only basic notes combined answer+extra into one label. Bigger
card, gradient Show-Answer button matching the app's signature CTA
style instead of a duller flat teal, and the Undo button now hides
itself when there's nothing to undo instead of sitting there disabled
looking identical to a real action.
Library: colored type badge per card (Basic/Cloze) instead of plain
gray text, more breathing room inside each row, Study promoted to the
same gradient CTA style, and Edit/Archive given a real secondary
button treatment instead of default theme buttons. Note editor fields
renamed ("Back / Extra takeaway" + a separate "Extra" field was
genuinely confusing) and now show which deck a card is being saved to.
Import and export were stubbed with status-text placeholders; wire them
to the existing backend endpoints with a real file picker (web JS
bridge or native FileDialog) and browser/desktop download, plus an
import preview with create/update/skip/error counts before commit.
Also fix the library and study screens' theme-refresh handlers, which
were no-op stubs so cards never restyled on a theme toggle, and add
responsive layout handling for narrow viewports.
Adds a full flashcards system: FSRS-based scheduling, cloze/basic
card types, CSV import/export, media storage, and study UI, wired
into navigation and the dashboard alongside existing question flows.
