Excellent Rated 5 out of 5 stars
I managed to remove most of the standard search engines that shipped with this App, and without much grief, added a new one, to a dictionary in my mother tongue, using the specified %q string. I'm not a techie, and if I can do it, anybody can.
I have also added search capability for ixquick.com, using the shortcut 's' and "http://ixquick.com/do/search?q=%q". Google is 'g' shortcut and "http://www.google.co.uk/search?hl=en&q=%q" (my choice of UK)
