Layer Up / Layer Down
Seriously, this might be the most useful menu commands I’ve every made. I use them every day, dozens of times a day.
Add these menu commands and give them keyboard shortcuts. Use the keyboard shortcuts to take the selected object or objects on the active layer and move the to the layer above or the layer below. If you run it again within 5 seconds it will work again, allowing you to run objects up and down the design layer stack.
