Creating a "It belongs in a musem" + "map markers mod" need pointers

Eh, shame. If there was a way, and there even might be, to set a tag on an item placed somewhere, then a removeitem/placeitem could be used for at least some moderate cleaning. You'd lose your krong and CoE stuff, but you'd be able to clean up "regular" stuff you might be using, like cybercones, mana toruses, rare good enough build specific drops and stuff...
