RE: Never forget anything again...
You can do much the same thing.
Make small labels for each major component you take to the flying field.
Attach the labels to cloths pins, and put them all on your sun-visor.
When you are ready to load up, take each pin from visor and place on/in
Flight box or tack-box.
IF there are any pins left, you will notice them BEFORE you leave.
Safe and Happy Flying.
