If you have already created one or more model files, each will appear in this panel as an icon. Double-clicking the item of the model you wish to load creates a new MySQL Model tab and displays your model.
If you already have created a connection to a database, it will appear in this panel as an icon. Double-clicking the icon directly launches an SQL Editor tab, and connects you to the database as defined by the connection.
