2Q/ZQ have available a ridgeline organizing hanger- 3 or 4 pockets..lightweight and folds up easy.
That looks pretty cool. I never thought about using velcro to secure the bag to the ridge line. I would just use a line. I don't want that organizer though. I would rather use a stuff sack type thing. I wouldn't want a dedicated organizer. I like multiple use objects, so I would want my "night stand" to also be the stuff sack for the hammock.
