A couple of my favorite new item todos:

First thing I do with a trash can is drill some holes a few inches from the bottom. When the bag is full the holes will let in some air and make bag removal much easier. Keep the holes away from the bottom to reduce the risk of a broken bag leaking any spilled liquids.

The containers of salt I buy have the classic flip top aluminum pour spout. The tip of the spout can be bent away from the lid to aid in opening and reduce the risk of fingernail injury.
