Great but 2 buts

1) I found a bug, that makes “content” of the slider not match the background if background minimal height is set. I fixed it via this code:

/* Smart Slider fixup */

.n2-ow {
  margin: 0px !important;
}

div#n2-ss-2 .n2-ss-section-outer {
  min-height: 400px !important;
}

2) I was unable to find an official way to give feedback about that at plugin official website.
