Quests and Key Items

Will there ever be a way to delete quests you may have inadvertently started but never intend to finish? Also any way to delete key items that there is no use for? Sure would like to clear up my logs from some of this stuff that has been in there for years!

Do you mean rid yourself of "Key Items" or R/Ex items?

As for questlog, its good to look back on some unfinished business. It gives me something to do while waiting for events to happen.
