1. Right now when using jsexec -D and pressing cursor up just gives ^[[A. It would be nice if the cursor would scroll through previous commands, similar to using a shell to go through command history.

2. Print the line that is about to be executed, similar to the perl debugger, so you can see what line is going to be executed rather than having to refer back to the code.

3. Add w (watch) that will show when the contents of a variable changes and its former and new values.

That's all for now. Thank you.
