I love the feature to screw it to the wall. Question though, instead of dowels, dominoes, etc what about a different joint type or even make an extendable ladder? I ask because I have multiple family who all want custom sizes and yet once I give them theirs they regret not going taller or it’s hard for them to travel with because they can’t knock it down in the car. I think it’d be neat to make it knockdown like the stools or even just to see a different joint type like through tenons on the slats
