I've worked on and off with Drupal for a few years.
One thing that has bothered me a bit, is that the admin toolbar at the top doesn't give you the full flavour of what the public will see.
I usually get around this by using a second browser where I'm not logged in.
I wonder if there is a simple url parameter or some other setting that can turn off or hide the toolbar for testing display.
searching the web reveals a trick with some permissions.
But using a second browser seems easier as I'll want this for just a few minutes at a time.
Could I write a simple plugin that will catch some url parameter and hide the admin toolbar, is there such a thing already?
