0.1.0 — Pre-Alpha · Kandown changelog

First release. File-based Kanban engine backed by plain markdown — zero backend, zero database, no account, AI-agent friendly.

Core

Task files (tasks/*.md) are the single source of truth — title, status, order, priority, tags, assignee, subtasks, notes, and completion reports all live in one markdown file per task.
Board columns derived from task frontmatter status field, with custom columns stored in kandown.json.
Unknown task statuses appear as temporary columns in the UI until explicitly added to settings.
Drag-and-drop between columns with optimistic file writes and automatic rollback on failure.
Reorder tasks within a column by drag.
Task drawer for editing title, metadata fields, subtasks, and body content with 150ms debounced autosave.
Subtask progress tracking on board cards (checkbox count).
Guarded card deletion — hover trash icon, first click arms, second click confirms.
Keyboard shortcut ⌘⌫ / Ctrl+Backspace to delete current task from the drawer after confirmation.

Single-file web app (kandown.html) built with React 19, Vite, Tailwind CSS, and Zustand.
Uses the browser File System Access API — no server needed, works offline.
Board view and list view, toggled with ⌘1 / ⌘2.
Command palette (⌘K) for quick actions and task search.
Content search across titles, IDs, task body, subtasks, tags, assignee, and priority with highlighted preview snippets on cards.
Owner type filtering (human vs AI-agent tasks).
Filter bar with search input, active chips, and clear action.
Recent projects stored in IndexedDB for quick reopening.
Animated task counts with spring transitions.

Project-level theme modes: auto (follows system), light, dark.
5 built-in skins: Kandown (default), Graphite, Sage, Cobalt, Rose — all using shadcn-compatible CSS tokens.
5 font presets: Inter, System, Serif, Mono, Rounded.
Column color accents with expanded translucent backgrounds including black variants.
Cards blend into colored columns (50% white in light mode, 50% black in dark mode).
Tabler icons on board column headers for status visual scanning.

Dense settings sidebar with search, compact controls, and contextual hover help.
Configurable task metadata fields (priority, assignee, tags, due date, owner type, tools) — disabled fields hide across drawer, cards, list view, and filters.
