Use Dashboard
Dashboard is a home for older Apple widgets and is no longer used; but, it’s still available.
In System Preferences under Mission Control you’ll find a Dashboard dropdown. By default it’s turned off, but you can choose to display it as a space (desktop) or as an overlay (traditional). If you set it as a space it will show up as a desktop to the far left. Activate the overlay by pressing the Function + F12 keys.
As the Dashboard is virtually obsolete, some widgets will no longer work and you can only choose from the included options. You may be able to find and install others from the Web.
