opt-editor

Edit a document, undo and redo changes, save in-memory snapshots, preview saved content, and restore any version as one undoable change.

Render persisted content without mounting the editing engine.

Review changes with keyboard-accessible decisions: accept updates the document, reject keeps the original, and reset starts over.

Compose a custom authoring surface with BlockTree, BlockToolbar, document versions, and working undo/redo controls.

Edit headings, paragraphs, and a callout with Editor, defaultCatalog, and an in-memory document store.

A calm writing workspace with block editing, nested pages, page mentions, search, favorites, templates, local autosave, comments, Trash, and Markdown export.
