I named it after the function "previewInfo" which builts the box, but 
"disablePreviewNotification" is probably a better naming.

There are already settings to configure the message with
config.message_preview, so "disablePreviewMessage" would also make sense.

I'd vote for "disablePreviewNotification", so you don't get confused 
with mixing underscored and camelCased settings.

Andreas
