Lumia 640 start screen

[Windows Central Question]

Just got my Lumia 640 and restored my settings/backup from my recent backup from my L920. But now the L640 start page only uses about 2/3 of the width of the screen. I have a 4-column setup for my L920. How do I make the L640 to use the full width of the screen?

I think I know what happened. The L640 can have 6-columns for the smallest tile. I just need to add to the empty space with new tiles.
