First of all we need to load the editor. To do this click '
' on the left menu, once this drops down and gives you some more options, click '
'. Then select the page you would like to edit, finally click the '
' button in the top left.
Once inside the editor you will notice whenever you hover over a panel, a set of grey buttons will appear on the right side of the screen. When you click on the small '
' this will give you the option to remove the panel.
Once removed, the panel below will automatically move up to fill the space.
