This currently works for Genesis themes as I can test that, but a ‘one size fits all’ template may not work well with all themes so I did not include one in the plugin.
You can create a landing page template for your child theme and associate it with the target page to achieve the same result.
I was talking more about removing the address bar from the browser, so that it’s just a window. Wouldn’t really have to do with the theme, right?
In the pre IE5.5 days we could achieve this when opening a window with javascript. Back then we could use titlebar=no & location=no however these parameters are ignored by modern browsers as a security measure.
