# Application Preferences

Logisim supports two categories of configuration options: application preferences and project options. The application preferences address preferences that span all open projects, whereas project options are specific to that one project. This section discusses application preferences; project options are described in another section.

You can view and edit application preferences via the Preferences... option from the File menu (or, under Mac OS, the Logisim menu), a window will appear with several tabs. We will discuss these tabs separately, and then we will see how preferences can be configured from the command line.
