In my last game, I had a Scout-character which was quite good at "foraging". Since I found a mass of "hammers" in the town, I had no use for the non-sharp stones after a while. Nonetheless, I found tons of it. Soon later, I had around 50-100 twigs and other wood-stuff. That was the time I wished, there was a "destroy item"-button in the game. Of course, you can let the stuff right there where you found it (on the ground). But I don't want to litter with the stuff all of the world. I can imagine, this will lead some time to problems with stability of the save file, since the data of the world gets bigger and bigger. Or maybe you could make it possible to check individually, what items get foraged, so you uncheck with a click, if you don't want to search for non-sharp stones any more. So it shows you only the stuff, you didn't uncheck in a foraging-menu...
