i wouldnt mind labelings, but i never find inside-visible-containers great and would love to shout a big NO.
thieves should take longer time looting, personally i even want them to leave scents for every container they check, you know how real life thieves leave fingerprints if not wearing gloves, but that is off-topic here.
to me, losing track of where you put what is your own laziness and lack of organizing abilities, or maybe the sign of getting old, like me.
