<![CDATA[Opera CLI switches and --headless]]>Does Opera support the --headless switch properly, or will Opera support --headless in the future, like chromium and chrome.

I tried it on Opera Developer/Beta, it runs, it hides the main window, doesn't show anything except the menu

Is there a list of all command line switches available for Opera, something like
http://peter.sh/experiments/chromium-command-line-switches/

opera-developer --help doesn't help much.

And my question is: which do and which don't?

You will need to test them or try to find a list somewhere. There isn't anything official on it.

Can opera do the same somewhere?

I don't think so.

Somehow Peter Beverlo can generate that list for Chromium automatically.

Can opera do the same somewhere?

Or supporting opera--help or man opera with up-to date info would be a good start.
