You may want to look at:
Wiring for a future alarm system (doors and windows)
Wiring for future camera system (front, back, and inside locations)
Many people like the tile on a diagonal.
Second towel racks in all bathrooms
LED under counter lighting and top lighting is MUCH cheaper after you move in.
Insulated garage door, windows in the garage door.
Floor options for Lanai and Birdcage.
Sun reducing screening in the birdcage (we used 50% reduction).
Additional electrical wiring in the birdcage and lanai.
Floor receptacle in the living room, this avoids cords running along the floor if you want table lamps.
Stone counter tops, everywhere.

Hope this helps
