ok... I tried to use the forum search to see if there was a similar suggestion... but it returned a lot of people telling people to search the forum because they had made a duplicate suggestion thread, and also a lot of suggestions for the site finder...
ANYWAY... my suggestion/idea, which I'm sure is not unique or totally original, is that a search site option would be useful in adventure mode...
Picture this: You and your merry band of meat shields have just killed off a small hoard of Goblins in their little camp out in the woods. There were many of them, they out numbered you two to one and you lost several fine men and women... now there is equipment strewn all about the place... some of it you, yourself threw at the Goblin scum, some of it they stole from nearby towns... you wander round the camp [l]ooking at things trying to find that masterwork silver hammer that you know you saw a goblin use to beat Urist 238 into a red pulpy mass.
Sadly there are hundreds of items all over the place... and the fact the goblin bowmen, crossbowmen and even you have covered the area in fired and thrown silver / weapons makes it even harder to find that one silver weapon which may or may not be covered by a slumped goblin corpse.
The same applies to armour, every time a limb got chopped off and a Goblin lost his grip on a glove, there's another [ making it harder to find the real loot.
Wouldn't it be great if you could, once the area was secured (by the elimination of hostiles mobs), just have time pass and then get a trade style list of every object in the area, so that you could pick up the stuff you want or had lost to throwing.
Preferably it would be sortable and searchable/filterable. The time it would take to search an area could be reduced by having a higher observation skill and more people assisting you. Searches could be interrupted by monsters or even the return of any bandits/residents that were away for the main fight.
