Thank you for the feedback. We might have to start generating .png outputs - that will definitely solve the quality problem. Do you mind sharing the site/input you used?
Plus, the PNG doe not perfectly reflect our site (alignment problems , ...). Input site : http://d-sight.com
Finally, clicking on our screenshot brings us to "realtywarp.com"
Other wise it's a nice tool-to-have. I would probably use it around once a month.
