Lock items in bag preventing from accidentally dropping them

In order to prevent dropping items accidentally from bag, I think it would be nice to lock them into the bag area similar as bound items that cannot be dropped. You can always lock and unlock the item. Obviously, you can still drop them if you get killed without zem. There is a similar feature with a window that asks for dropping the item with an emerging windiw. I think this feature is old and a "padlock" for locking items would be safer since you can accidentally click and drop the item with the current system.

Thanks!
