Vim-inspired, as in it's minimal and fast, text editor on the web. No modal-editing yet but, once the current natural input mode is decoupled, clients can bring their own modes/controllers via the extension system.

It's meant to be embeddable and hackable, serving as a building block for custom IDEs as opposed to being IDE-like VSCode. I felt the web IDE space was uninspired with apps built around VScode/Monaco effectively being hosted a VSCode instance with a pre-installed extension and config.json. (Aside: perhaps there's a business opportunity for VSCode-as-a-service where client apps simply bring their own config). I'm dogfooding this library in building an algo trading IDE.

Ships 2kb and smoothly handles 50+ million line files. 1 billion lines with the high-capacity extension. Also, it can function as a TUI or terminal on the web because the core implementation concerns efficiently rendering plaintext in a fixed-width grid layout.
