I was not consciously looking for Easter Eggs however I did notice a couple of things I have not seen listed yet…
Kirk about to die unless someone could get the transporter to work… (Doomsday Machine)
Shuttle Craft at the academy named “Gillian”… (Star Trek IV)
“I have been and ever shall be… your friend”… (Star Trek II and III)
"Space is Disease and Danger wrapped and Darkness and Silence”
