Currently the v3.3 beta is available to existing customers, and provided there are no major issues picked up during this beta testing phase, we could be looking at release in the next couple of weeks. This of course is approximate. Thanks.
You can make changes by way of customizing the default theme layout, and in doing so we recommend the use of a child theme. You can also find other layout options in the form of other child themes available in the AppThemes marketplace. Thanks.
