This tab is in the Debug tab.
The Generate tab allows you to generate pseudo-random Team and People records for testing and debugging.
Enter the number of Teams and People to create and press the Generate button. Each time you press the button, more records are generated.
The Random Seed field allows you to specify a seed value to the random number generator in order to cause it to generate the same records on two different runs. This assumes that the database on each run starts with identical Team and People entries.
