I have a feature request if it would be possible. I finally got around to coloring up my site and was thinking a thin 1 pixel border option for the following items would be something a lot of people would like and would really spice up their sites.
Content, Navigation, Widgets
Maybe some other things too that I can’t think of right now, but here’s a site to give an example of what I mean: https://www.tukui.org/addons.php and https://www.tukui.org/addons.php?id=38
Added Note: I just realized you could set transparency in the colors… AMAZING!!!
