I am deliberately putting this in the wrong forum as it is related to the label bugs I have reported and might be most appropriately addressed at the same time.
As we are not perfect in knowing our future needs, we sometimes wish to add a default attribute to a label. This does not, of course, propagate across all existing uses of the label. It would be useful if the edit label function of notes were to list new and deleted default attributes (perhaps dimmed) to remind the user of the "missing" attributes and provide the correct name for the attribute (minimizing typos).
Not a concrete suggestion but thought might also be given as to how to show the user the names for additional attributes that have been used on this label. At the moment the list appears to be unscreened which also has its place.
