A few other homages to earlier films that I noticed: the apparent “death” of Bond in the pre-title sequence(”You Only Live Twice”), the villain’s sacrificial lamb girl in Macau and her shower scene(”The Man With The Golden Gun”), Bond chasing the bad guys atop a moving train(”Octopussy”).
The ejector seat button (Goldfinger) The glass panels mirroring the killer and Bond in the sniper scene in the high rise (Man With The Golden Gun).
Nice to see Moneypenny and Q even if new faces.
Reference to exploding pens (Never Say Never).
The yacht motoring up to Silva’s island seemed to be an homage to a similar scene in Dr. No.
