Personally, I hate boxes because of object permanence. The best way to hide stuff is to put it in a box or a wardrobe: Everything is instantly gone.
When working on an idea, I often have little notes lying around on a table: The position, rotation and even if a note touches others contains relevant information.
Sure, looks like chaos for another person. They can keep their linear lists and little excel sheets, if they want. :blobcatgiggle:
