In the recent feat, people complained they kept accidentally dropping their conch. Normally you could just pick it up again, but there's also the problem of accidentally donating or giving away an item you really wanted to keep (icons way too close to each other, easy to click the wrong one).
Could we have a special bag (buy from hardware vendors, maybe with limited space) that keeps items 'hidden'? Anything in that bag doesn't come up under the donating or giving menus and doesn't have a drop option. This would prevent these accidents which can be very annoying with rare/valuable items.
I also saw a suggestion that there should be an upgrade which allows you to make items unable to be dropped, but I think this would just be annoying as it would add yet another option to every item.
