• Standard unix commands (available on both Linux and OS X preferably) that ShellJS is missing
• Performance improvements
• Making things behave more like POSIX

Most commands run independently of each other, so this makes it pretty easy to contribute a new command. If you'd like to do this, just copy a command from src/ and use that as a template for your new command. Update the documentation (it's in a comment above the function declaration) and run node scripts/generate-docs.js to update the README. Lastly, write unit tests in the test/ folder (copy another file in that folder to use as a template).
