A thought occurred to me during my last playthrough; while ingame and selecting preps, there really is no good way of determining which items are "quest items" as opposed to "elite items." The codex doesn't specify either, and though the info is in the wiki, it isn't really self-contained per se. Would it be possible to either add an additional small icon to item descriptions that show if they are normal, elite, or quest items? Another alternative would be to change the color of the item text based on its "tier" (a la WoW, Diablo, Dungeon Siege, etc).
Just an idea. Getting really excited for this game to finally get released!
