It would be nice to have an option to select different Google maps that are themed/styled/shaded with your site's theme. For example, this site allows you to do just that.
A real world example would be my site http://projectsixteen.com - currently the theme is red, white, blue, black and white. The regular Google maps is multicolored and doesn't fit well.
Hopefully we can get this integrated into Strikingly.
