Ahh yes, that had crossed my mind but I didn't mention it for not wanting to get into too much design detail for fear I would be embarassed by a deathly silence of lack of demand for the plugin at all...
The challenge I see with that particular feature (which I agree would be useful) is how to handle a user moving a row that they have locked/assigned a particular series number on.
You also have to handle the situation of a user moving "too many" rows before that assigned value such that the numbering overlaps. A visual warning on screen may suffice like an icon with a tooltip on such rows. Not insurmountable problems though - and as you have suggested a useful addition for those who don't create empty books.
