'Bandboxing'. The word 'bandbox' I originally thought was fairly modern, perhaps having its origins in the early 20th. century coinciding with the advent of radio. In fact, according to the Greater Oxford Dictionary, it comes to us from the 17th. century, first being coined in 1631. It generally means 'neatness' or 'pristine'. Here are a couple of lines from the dictionary :-
1869 _Mark Twain' Innoc. Abroad xxxviii. 410 They are all_ exceedingly neat and cleanly_as if they were just out of a band-box.
967 V. H. Gielgud Conduct of Member xx. 160 She was wearing a dressing-gown_but preserved her usual band-box quality of neat fastidiousness.
So, perhaps when we'bandbox' sectors we're 'neatening or tidying up'.
