Draw a border around groups if scrollbars are overlayed i.e. Lion

When you have multiple groups and no file is selected yet, there is no distinction between where the groups begin and end. If you have scrollbars overlayed (as Lion does by default) there's no break between files unless you have minimap or line numbers turned on, and even then it looks a little messy.

Perhaps just a setting to change the background color of the gutter?
yes please, it also makes it very tricky to move the border.
