As the improvements were pretty clear, I ran a update script over all the levels. Some still look a little rough, but all have been updated. You may need to clear your browser cache or press CTRL+Shift+R to see the updated versions.
And @raspatan wanted to be able to see information about the backgrounds. You can now. A simple click on some of the clear space on the pages should give you a context box with details and a link to map review page. The context box may take a few seconds to load as it is dynamic. This feature may not work on the ..::LvL App or mobile versions of the site (at this stage).
