Here are two easy ones:
Narrow-depth USB charger that still allows the door to close (I did need to remove the plastic cover for the cigarette outlet)
Bonus: blue LED matches the rest of the blue dash lighting

Seat gap fillers -- these seemed unnecessary in my old 4Runner (so much space to fit your hand if you dropped anything in the gap) but on the LC it's a different story. Great spot to hold keys and the little nub at the end is useful for hanging a bag on the passenger side. Or you can flip them over and they are smooth.
