Can you run chrome headless?

[weseze]

Is it possible to have the chromedriver implementation of wraith testing run headless. Meaning I can still use my computer to do other things.

For every test it is now focussing on the Chrome window and it is impossible for me to do anything else on my computer.

It was my understanding this would be default? I would like to avoid having to setup a VM for testing.
