I had an idea that, if an item is locked in your inventory, it would not show up in your account value. This is a great way to check the price of items in your inventory. I don't like having to do math to subtract the price of a lizard minion set from my inventory worth total.
you mean... account worth? this suggestion seems a bit silly to me since I don't think people should be adjusting their account worth by masking it by locking it in their inventory.

I don't think it really matters that much since in most cases it can hardly affect your AW if your talking about achievements that and it could potentially be beneficial due to the stupidity of the AW system.
Such as the items worth like 13k (if even) being labeled as valued at 30m+ might help you get a better (ha) idea of your "true" account value
