I can't see where or how I can change it. Please explain it to me?

I do wish you would stop changing Opera. "Don't fix what aint broke".
I don't like the latest changes to Opera. When I save a page in my speed dial it now only shows a blue square with the website address on it. I liked the idea of having the exact image of the page I was trying to save not just a web address. When I look at my speed dial I like to see all the different images of the individual pages of a website that I have saved. Not just blank squares with only the web address - boring. Please put it back the way it was?
