1. Being able to capture more lines of output when running the script from the test tab. It seems now it is limited to a fixed number of lines, which means you could miss some output.
2. Being able to specify a custom time-out when running the script from the test tab. It now times out after 10 seconds.
3. When the test times out, the reply is set to: "Error: unable to execute the script". This is not true, a time out occured. This can be a confusing reply message, setting it to: "Error: Timed out" would be more clear.
