I noticed when creating a layout you have the option of top margin, side margin, and gutters. I currently have my top and side margins set to 0 dip with my gutters set to 8 dip. Although I have no margins on the layout, there is white space at the bottom of the layout after the last element. I assume this is from the 8 dip gutter; however, I do not understand why a gutter would appear after the last element.
It seems as though there should be no gutter if there is no more content in the layout, and instead there should be a bottom margin option. The current behavior prevents be from having a card flush to the bottom of my layout when I have a gutter.
