This comes from my spellbook crafting.
Thoughts behind:
1) At max crafting, there is a 70% success rate and a 20% exceptional rate.
2) Normal crafts don't get bonuses, only exceptional.
Therefore 3)  Only 20% (in theory) have bonuses.
Currently -moveitems moves exceptional crafts as well as normal crafts.
Is it possible to make "marked" items (exceptional items) not get part of non-marked items?  Or possibly make exceptional spellbooks craft with a different id (spellbooks with bonuses are only artifacts or exceptionally crafted from what I've read/noticed).  I know the jewelry had an auto-sort put in (for which I'm extremely grateful).  Is there a way to do this with spellbooks as well to where I only sift through the bonuses instead of every single non-bonus as well moving one at a time into the recycle bin?
