Besides some tweaking here and there with the async processing, image pre-loading and so forth, there is a new feature to turn on or off the recently added security feature. The current security feature uses the user’s security privileges to determine if a button is displayed and an entity button will only display if they have the Read access right to the specific Entity. Turning off the security feature prevents the Quick View Menu from making a number of web requests which may improve load performance.

This is an example of the Quick View Menu Solution Configuration page. Simply click the Security button to toggle security on or off.
