The Dashboard app provides a bird's eye view of status of your ClearOS system.
This app is installed by default.
You can find this feature in the top-level menu.
Here you choose which widget you'd like to have appear in that position of the main screen.
<note tip>The only way to remove a widget from the screen is to change the number of columns you which to appear in that row of the Settings screen. It may mean re-doing the whole row.</note>
