Open the Camera or Widget menu.
Select the desired cameras or widget from the opening list.

Maximize the grid
If you have empty cells in your grid, click Grid > Best fit. This will maximize grid or cell use and eliminate empty cells.
If after choosing Best fit you wish to go back to a grid with empty cells, you can do so by going to the Grid menu and choosing your preferred grid size. You can also customize the grid size by choosing Custom Grid.
The default grid size is 3 by 3, or "Nine". If you feel like you don't have enough space to adjust the size of items as needed, increase the grid size from the Grid menu and select a bigger grid.
