Yeah, the "reverse" flags is hardcoded to true right now ... Only because those need to be set together, but right now the sort tag = tag name, so some things assume they can just take the value and lookup the NodeTag for it. I just didn't get a chance to fix it so it's like "tagname,direction" and the couple of places that directly use that tag. It's on the list that will probably make the next build. I started to do it for 69 actually, but i cut it because 69 had some big fixes that i wanted to get out quicker.
