Hi there. This is my 1st feature request to this amazing engine, so here we go: Some time ago, I found the Gecko only supported property -moz-outline-radius, which seems quite interesting to me, as it could be used to style two borders on a container without additional markup (in example, of course). Other option is to make the outline follow it's container's radius, so if the container is set to 10px, then the outline should follow that radius without adding an additional property. It makes sense, even that I guess it's not included in CSS3 spec at all. Thank you so much!
