Kanban JSON

Minimal kanban editor for .knbn files. The board follows your color theme, and the JSON file stays the source of truth: undo, redo, git diffs, and external edits work like any text file.

Features

• Columns: add, rename (double-click the title), delete, reorder by dragging the header.
• Cards: add, edit title and description (click), delete, drag within and between columns.
• Color marks (red, orange, yellow, green, blue, purple), drawn with the theme's chart colors.
• Edits, including undo and redo, are saved immediately.
• Markdown links and bare URLs in titles and descriptions. Paths resolve relative to the board file, then the workspace. Click opens the file; Cmd/Ctrl+click opens it beside the board. The link button in the card editor inserts a workspace file.
• Kanban: Open as Text / Kanban: Open as Board in the editor title bar.
• JSON schema validation and completion in the text view.

Create a board with Kanban: New Board (command palette or a folder's context menu). An empty *.knbn file is initialized on open.

Enter saves a card title, Cmd/Ctrl+Enter saves the description, Esc cancels. Enter on a focused card starts editing.
