Hi,

1.You can use custom themes , here is a link on how to create a custom theme from an existing theme, I personally would reccomend using Granite:

2.You can also put a border around the checkpoint box in the format tab of the checkpoint's control properties.
3.If you are using a table in you view, you can change the background colour of eache individual table cell from the format tab.

Kind Regards
Prineel
