Shortboard IS JUST AN IDEA. No browser here yet.
Shortboard is a web browser designed with user privacy and control as paramount features.
Shortboard will use the Servo web rendering engine. Servo is still in development. Servo is already more parallel than any other web rendering engine, and it will likely be the fastest and eventually most stable rendering engine thanks to the Rust language.
Features will be listed as they arrive. For intended features, see the Issue Tracking on github.
