Model overview
The model overview widget is a navigation support control that is extremely useful when the user is dealing with a large model.
Magnifier tool
Another way to navigate the database model is by using the magnifier tool.
Model objects
The model objects widget is used to organize the database objects hierarchically.
Object search
The object search widget is a tool that provides quick object searching over the model.
Layers management
The layers management widget allows the user to move graphical objects to multiple layers to create a contextualization between them or even to improve the model's visualization when the set of objects is too large to fit the entire canvas, for instance.
Source code preview
Another interesting tool is the source code preview which permits the user to visualize the source code of one object or more selected objects on the fly without the need to export them to a SQL file (in the case of SQL code) or to open the database model file in a text editor (in the case of XML definition).
