The widgets that are displayed on your Dashboard are unique to your user profile. You can have as many or as few as you like displaying and the system will remember your options for the next time you login.
We periodically add new widgets so if you click the blue 'Add Widget' button then you can see if there are any others which you might find useful.
You can move widgets around by dragging and dopping them in different places or orders on the dashboard screen. You can also use the 'cog' icon to make them bigger or smaller or indeed remove them if you don't need them.
If you remove a widget by accident, you can always add it again using the 'Add Widget' button.
