I thought of a couple of things that I do.
Crouching down has become difficult for me. Finding things on the bottom shelf of the refrigerator is particular challenge. I started using baker's half sheets on the bottom shelf to act ike a poor man's slide-out shelf. They have the added advantage of being easily cleaned if meat juices and the like spill on them.
After a real "Duh!" moment I realized that I could use a measuring cup for the rinse aid for my dishwasher and pour it in without risking overflow. For my machine it's 3 ounces.
