I think it would be nice if there was a way to move the layers of the ornaments around in the list of the ones you have added to your tree. (Kind of like when you putt clothes on your ha)
I don't really see a point to this since you still need to adjust their position anyway, and if you want your list of ornaments in a specific order for some reason you can just add them to the tree in that order?
That would be great actually, because as it is now, if you decide you need things layered differently (e.g. you get all your ornaments on and THEN decide you want a string of lights), it seems you have to remove all the ornaments and then add the lights, if you want the light string to appear under your ornaments (which of course you do). It ends up being pretty frustrating having to redo everything in that scenario. It's not just about the list, it's how the layers are displayed on the tree.
Unless there is already some other way to adjust the layering that i wasn't finding. Redoing everything was the only way i could see to fix it.
