Buttons can be prioritized by their position on the page or by their size. A button can be emphasized by making it larger than the others on a page.
If you are increasing the size of the button, the button will expand to the right or down. The button will draw over the buttons to the right or below it, rearranging buttons as needed. If the button is already in the far left or right column or the bottom row, move the button to the left or up to provide additional space.
Select Menu > Edit Mode.
Select and hold the button that you want to resize.
Select Change Button Size.
Set the number of cells you want the button to fill both vertically and horizontally.
Select Save. The button will fill the number of cells you set.
