Just an idea, but for lonesome road (or any future updates) do you think that a terminal in the lucky 38 pres. suite that could remove quest items and add them back into your inventory would work? Or if we cant put them back in our inventory we can just remove them? You can warn us before hand of any risks of failing quests etc. if we remove them.
I don't know about that, but PS3's Ring a Ding Ding, Eyesight for the Blind, and Dead Money are guilty of leaving useless trash in your inventory. :facepalm:
These are why I'm glad I play on a PC. I absolutely
hate having useless quest-related crap cluttering my inventory even though it doesn't weigh anything, so I made an .esp file in which I disable the 'Quest Item' tag on such things, which lets me stick them in a crate when I don't need them anymore.
For those on console systems who don't have this option I wholeheartedly support the OP's idea, as it's clear I'm not the only one this really annoys.
