Roadmap

• A browser-only engine (DuckDB-WASM or hyparquet in a worker) for apps without a server.
• Editing cells, with CSV write-back that keeps untouched rows byte for byte.
• Formula columns.
• Showing the first rows of a sort of 100M+ rows while the rest is ordered.
• Excel (.xlsx) input.

Ideas and use cases are welcome in the issues. Open one before a larger pull request, as CONTRIBUTING.md describes.
