[0.1.0] · MVP

Architecture

WYSIWYG editor built on TipTap 3 (individual extensions, no starter-kit); toolbar active-states stay reactive via a tick counter (Svelte 5 same-reference workaround)
Fixed A4 paper canvas (794 × 1123 px @ 96 dpi) with CSS-simulated pagination and visual page breaks
LocalStorage auto-save (debounced 1 s); restores document, theme, zoom, margins, orientation, etc. on reload
Fully client-side / serverless; hand-coded SVG favicon (no external assets)
Placeholder text on an empty document

Text formatting

Bold, Italic, Underline, Strikethrough
Subscript / Superscript
Font family picker (lists only fonts installed on the machine; remembers recently used fonts)
Font size
Font color and highlight color (color picker with custom colors)
Headings H1–H3, including un-bolding a heading

Paragraphs & lists

Text alignment: left, center, right, justify
Line spacing and paragraph spacing (space before / after)
Increase / decrease indent (paragraphs and lists)
Bulleted and ordered lists — nested, with multiple numbering styles (decimal, alpha, roman; . or ) suffix) and whole-list indent; Tab / Shift-Tab to nest / un-nest
Tab stops (real tab character) and manual line breaks (Shift+Enter)

Insert

Tables: insert via size picker, Word-style row/column drag-resize, add / delete rows & columns, delete table, cell borders, merge cells and split cells (N×M, Word/LibreOffice-style), cell background shading, header-row toggle (bold + shading); a table splits cleanly across page boundaries
Images: inline or floating with text wrap (left / right / top-bottom), resize handles, rotation, live size badge; insert via toolbar, drag-and-drop, or paste
Special characters picker
Table of contents: generated from headings (H1–H3) with live page numbers and dot leaders, click an entry to jump to its heading; round-trips to ODF text:table-of-content and a Word TOC field
Hyperlinks: create / edit / remove (toolbar + Ctrl+K), Ctrl/Cmd+click to open, hover hint showing the URL; ODF text:a round-trip
Manual page break (Ctrl+Enter); round-trips to ODF fo:break-before

Page & layout

Page margins (cm) and page orientation (portrait / landscape)
Headers & footers with page-number / page-count fields and configurable edge distances
Zoom (20–300 %)
Show formatting marks (spaces, tabs, paragraph marks)

Editing aids

Undo / Redo with a labelled history dropdown
Search & Replace (Ctrl+F / Ctrl+H): live match highlighting, match count, next / previous, match-case and whole-word options, replace current / replace all
Spell check in English with squiggles and a suggestions context menu (add / ignore word); selectable document language
Word / character count statistics (whole document and selection)

UI & theming

Light / Dark / AllBlack / Auto appearance modes (settings menu in toolbar)
Primary toolbar plus an expandable extended toolbar (horizontal scroll on narrow windows)
Status bar with page number, word count, language and zoom controls
About dialog

File & export

ODT export via odf-kit with extensive content.xml / styles.xml post-processing (custom node types, tables with borders, images, fonts and colors); filename derived from the first heading (fallback document.odt)
ODT import / open existing file: parses content.xml / styles.xml directly, adopts the file's margins and orientation, and reports graceful-degradation warnings
Word (.docx) export and import — round-trips the editor's formatting (text, fonts, lists, tables, images, headers/footers, page geometry) and opens real Word documents
PDF export — Raster (pixel-exact copy of the editor with a selectable text layer) and Vector (crisp, fonts embedded, via the browser print dialog)
Print (printer button / Ctrl+P) — opens the browser print dialog with a pixel-exact raster of the document (tables, headers/footers and page breaks intact)

Planned word-processor features (to match Word/LibreOffice):

Other:

Zoom 100% does not visually match Word/LibreOffice at 100% on the same screen. Root cause: the editor uses the browser's fixed 96 CSS DPI (794×1123 px for A4 — see editor.css, pageBreaks.ts), while Word and LibreOffice render against the OS-reported physical screen DPI so that 1 cm on paper ≈ 1 cm on screen. Possible future fix: add a user-side calibration (DPI value or visual ruler) that scales the zoom factor. Decided 2026-05-26 not worth the effort for now.
Lists and headings inside a table cell are exported as plain text, not as real ODF structures. odf-kit's CellBuilder is run-based (text runs only), so a cell cannot hold a true <text:list> or <text:h>. On export (export/odt.ts): headings render as bold runs at the heading font size, and list items render as separate lines with literal markers (•, 1., 2.…), nested lists indented. Content is preserved and readable, but loses list/heading semantics (no auto-numbering, not recognised as a heading). Noted 2026-06-06.
