Currently the panels in CM-Neo (explorer, properties, toolbar) are refreshed triggered by the onload event of the website panel. This event however is fired after the complete content is loaded (scripts, css, images, videos, ...). Depending on the content this may take some time.

This now has been changed.

We now inject a peace of javascript inside the web page (if rendered in contentmanager) informing CM-Neo that the page that will be loaded. This gives CM a chance to refresh its panels quickly.
