• Use the new mechanize (don't require progress_bar is mechanize version > 1.0)
• Cache form submits
• Show page.body in browser

And Nokogiri needs this:

class Nokogiri::XML::Element; 
    def better_text; 
        result = []; traverse{|x| result << x.text if x.text? }
        result.join(" ").strip
    end
end
