[Dillo-dev]contrast_visited_color

Hi there, I've been playing with this patch for enough time to start to like its effects. It changes the old 'force_visited_color' dillorc option with 'contrast_visited_color' (featuring a new algorithm). This allows Dillo to choose the visited link color, in such a way that it makes good contrast with the rest of the page. Please update your dillorc with the new option, test it, and say how it works for you. A suggestion: http://www.paulgraham.com (any link). -- Cheers Jorge.-
