In addition to Quantum-based functions, VNgen includes a second category of functions intended to be used in a separate object from the main script, which then records text and voice actions in a list for reviewing later. This visual history is called the backlog.
Using a backlog object is optional, and adding data to it is automatic. Nevertheless, while little developer action is required, VNgen provides as many options as possible for creating and customizing the backlog for those who want it.
In this section we'll examine available backlog functions as well as a variety of navigation methods designed to suit any platform.
