How can I integrate Simplicity IDE and the primary Simplicity window?
By default, Simplicity Studio will present the home screen whenever started and spawn a new window when Simplicity IDE is opened. This behavior can be modified so that the IDE is presented in the same window as the home screen.
To control this, click Settings in the Simplicity Studio home screen or Window > Preferences in Simplicity IDE. Then navigate to SimplicityStudio > Launcher. Several settings are available.
If Start in last screen used is selected, it is recommended that Open integrated tools in the same window also be chosen, since the behavior of this combination may be unintuitive.
