Ocideck/CHANGELOG.md

# Changelog

All notable changes to OciDeck are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and the project aims to follow [Semantic Versioning](https://semver.org/).

## [Unreleased]

### Added
- **Duplicate clean-up in the image library** — a footer button finds
  byte-identical images by md5 checksum, keeps one file per group (preferring
  the one used in slides, then the oldest), merges the tags/descriptions and
  captions of the copies onto it, repoints slides that used a copy — in open
  decks and in `.md` presentations on disk that are not currently open — and
  deletes the copies after confirmation.
- **Untagged-images filter in the image library** — a toggle next to the search
  box shows only images without a description/tags, making it easy to see which
  ones still need attention.
- **Delete warning covers decks on disk** — deleting an image from the library
  now also warns when presentations that are not currently open still
  reference it.
- **Source-code slides** — a "code sheet" with per-language syntax highlighting,
  stored as a fenced code block. Background, text colour and monospace font are
  part of the style profile, with a syntax-colouring toggle; turning it off renders
  the block in a single colour (e.g. green on black for a CRT-terminal look). The
  code is sized to fill the panel — larger when there's room, smaller for long
  fragments.
- **Charts** — bar, line, pie, and **spider/radar** chart slides. Data is entered
  in an in-app grid or imported from CSV; the spec is stored as JSON in a ```chart
  block. Data can stay inline or be linked to a CSV in a separate `data/`
  directory. Rendered natively in-app (preview, presenter, PDF, PPTX) and as
  self-contained SVG in the HTML export.
  - Optional **min/max**: horizontal reference lines on bar/line charts, or a
    fixed scale on spider/radar charts shown as a small legend beside the figure.
  - **Legend hover** highlights the matching series (or pie slice). Line-chart
    tooltips attach to the dot under the cursor (showing every overlapping dot),
    and spider/radar points show a tooltip on hover too.
- **Custom theme colours** — every style-profile colour can be entered as a custom
  hex value in addition to the presets.
- **Per-slide TLP classification** — each slide can carry its own Traffic Light
  Protocol level; slides classified stricter than the level the deck is shown at
  are withheld when presenting and exporting.
- **Export release ceiling** — an optional maximum TLP level that may be
  exported. When set, a deck classified *above* it cannot be exported in any
  format; the gate is enforced at the single export chokepoint and fails closed
  (no file is written when blocked, and the export dialog explains why).
  Classifying a deck stays optional — the ceiling only stops decks that exceed
  it, and it is off by default.
- **Dual-screen presenter** — on a second display the beamer shows the slide
  while the laptop shows the presenter view (current/next slide, notes, timer),
  kept in sync over method channels.
- **Annotation layer** — draw on slides while presenting (pen, highlighter,
  eraser, laser pointer). Kept fully separate from the Marp Markdown, mirrored
  live to the beamer, and persisted in a `<name>.ink.json` sidecar.
- **App theming** — customizable app appearance profiles, including a dark
  interface.
- **Paste a table into a table cell** — pasting a spreadsheet selection (Excel,
  Numbers, LibreOffice Calc, Google Sheets), CSV (comma or semicolon), or a
  markdown table into any cell of the table editor fills the whole grid from
  that cell, growing rows and columns as needed. Works with `Ctrl/Cmd+V` and
  `Shift+Insert` on macOS, Windows, and Linux; plain text still pastes into the
  single cell.
- **Slide-type chooser previews** — the add-slide dialog shows a miniature
  wireframe of each layout (in the spirit of other presentation tools) instead
  of an abstract icon, and is fully keyboard-operable (`Tab`/`Enter`/`Esc`).
- **Accessibility (WCAG 2.1)**:
  - An **interface text size** setting (100–200%, Settings → General →
    Accessibility) that scales all editor text; slides themselves keep their
    fixed design size.
  - The panel divider is focusable and **keyboard-resizable** (arrow keys), with
    a visible focus state, and presents itself to screen readers as a slider.
  - **Screen-reader support**: slide thumbnails announce one concise label
    ("Slide 3/12: title") instead of their full content; charts expose their
    type, title, and underlying values as a text alternative; the presenter
    announces each slide change.
  - Improved contrast for hint/label text in the editors.
- Project documentation: contributing guide, security policy, architecture and
  build notes, user guide, keyboard-shortcut reference, third-party notices, and
  the EUPL-1.2 licence text.

### Changed
- **Bullet slides** can now carry an optional **subheading** under the title; the
  **two bullet columns** type can have an optional **heading above each column**,
  separate from the slide title.
- Slide text auto-sizing now measures with the deck's own font, so text grows to
  use the available space more accurately instead of staying smaller than needed.
- The two bullet columns are measured **independently** and then rendered at a
  **shared size** set by the busiest column, so the two columns always look
  typographically related. Dense two-column slides spend less height on the
  title, headings, and gaps so the list items themselves render larger.
- Slide transitions in the presenter no longer flash a black frame (neighbour
  images are precached and `gaplessPlayback` is enabled) — important for
  recording.
- **Spider/radar charts** now use the available space: axis labels are measured
  and placed snugly around the polygon (up to three lines, full remaining
  width), so the diagram renders considerably larger and long labels stay
  readable instead of being truncated.
- Bullet auto-fit now stops growing at ≈32 pt (on a 16:9 deck) — the upper end
  of the 24–32 pt range presentation-design guidance recommends for body text —
  so slides with few bullets no longer render body text that competes with the
  title.
- After resizing the slide panel (dragging the divider or resizing the window),
  the list scrolls the slide being edited back into view.

### Fixed
- Hover on charts (tooltips, legend highlight) now works on a second screen:
  macOS only delivered mouse-moved events to the key window, so the borderless
  beamer window never saw them; the stuck hover state after the pointer left a
  window is gone for the same reason.
- Bar-chart x-axis labels could run through each other: the spacing maths now
  matches how bar groups are actually laid out, and the final label shrinks to
  the real gap when it sits closer than a full step.
- A crash in the slide list ("A _RenderLayoutBuilder was mutated…") when its
  keyed items were rebuilt during layout — both the resize-detection inside the
  panel and the shell's width computation now avoid LayoutBuilders above the
  reorderable list.

## [1.0.0]

### Added
- Initial release: structured, slide-by-slide editor for Marp presentations with
  typed slide templates, live preview, fullscreen presenter, deck-wide TLP
  marking, media handling, import, and export to Marp Markdown, PDF, PPTX, and
  self-contained HTML. Decks save as a self-contained project/package with copied
  assets. Localized in Dutch, English, Italian, German, French, Spanish, Frisian,
  and Papiamento.
