Sometimes I want to keep an item in my backpack so I can haul it out the second I need it, rather than having to teleport home to retrieve it. But the downside is the risk of accidentally selling the item when you're selling off loot. So, I was thinking it might be cool if there was a little padlock icon next to each backpack item, so you could lockout an item that you want to keep in your backpack, but don't want to be able to sell.
