Had Redirect Control (Not Compatible for Optimum) which gave you the option to block, allow or add rule "POP OUT"
"Add Rule" was good and simple when purchases redirect to submit payment confirmed etc,

Also had a simpler Black List, White List Editor.
This would be great update in Skip Redirect. Other than that is works great.
