Zoombox is a flexible, half-modal, half-tooltip plugin.
Out-of-the-box it does very little and relies on the client-coder to do most of the lifting. Like many things in life, you get what you give.
If you are using zoombox and have a feature request or bug report, please file it at the Issue queue.
