I hope I'm not the only one that finds it extremely disorienting to have all my photos neatly arranged and sorted, only to click the "Change" button and have them immediately locked into numerical order, with no way to have any clue which one belongs to which room any more.
Numerical order is certainly helpful for making sure the "top five" are what we want. But most of my photo sorting time is spent trying to get them assigned to the correct rooms. It would be extremely handy to have a drop-down selector in edit mode (as there already is in non-edit mode!) to tell OR how we want them sorted. It would make assigning them to rooms so much easier if we could just drag-n-drop them to the correct headings instead of having to click "edit," find the room in the drop-down, and then click "close" on every one of them.
