A browser built with Electron that exposes Node.js and otherwise keeps away from the HTML5 kitchen sink, in order to push innovation away from the spec committees and back out to the community. Vital technology like TCP, UDP, DNS, and the filesystem is being locked up behind a fascade of poorly implemented APIs.
A browser with a small, efficient core, optimized for rendering, and with a brilliant app install system, and brilliant native cross-platform integration. The time is ripe.
