We're releasing v7.2.6 now which has a bunch of bug fixes for the v7.2 line. But along with these we've improved the Mega Menu default styling to make it a bit more "snazzy" and wanted to give you all a preview here on our demo store...
There is also a small but important change for the Dynamic CSS Menu as there is now a "+" indicator for those menu items which have sub-categories. You can see this on the Demo Store products pages here...
