When SQL Visualizer starts, the Start Page is displayed providing quick access to recently used files and other features.
The Recent Files list provides single click access to the most recently used files. When files are opened or saved they are added to the list, with the most recent file placed at the top.
The Start Page also provides access to visualizers and wizards.
You can prevent the Start Page from opening when the application starts (see changing options and preferences for more details)
