I'm reading through the Starfleet Academy comics on the DVD collection, and love to see some of the other characters pop up. We know they are in continuity thanks to Pava being on Titan, so I wouldn't be that weird to see Decker or T'Priel (if she sticks around, I haven't gotten the issues resolving her issues yet) pop up on one of the ships we follow. I'd be happy even if Pava just mentioned where they were serving and they were up to.
Omega Squad was also mentioned in
Mission Gamma: Cathedral, which alluded to, if not diectly mentioned, Matt Decker (something about Nog being in the squad with the great-grandson of a historic Starfleet Admiral). I would also like to see thiose characters again.
(Responding to JD: ) Well, just because a character from the comics shows up in the books, that doesn't mean the events of the comics necessarily happened in the main book continuity. It's an homage, using a fictional character in a different work of fiction. Starfleet Academy is a good series, but it has some questionable things continuity-wise, like a story where a character is in a transporter buffer for four days even though the safe limit is more like eight minutes except in extraordinary circumstances. And its handling of Talos IV in the "Telepath War" arc is incompatible with Burning Dreams.
Well, the cadets trip to Talos IV, which was the set-up for the Telepathy War, was also mention in
MG:Cathedral. And all we saw of Talos in
SA was a Jem Hadar infested battlefield, so the cities and the Talosian civilization seen in
BD might still have been there, perhaps on another continent. And even though
BD mentioned something about the Talosians applying for Federation membership, to my knowledge, this has never been followed up on.
I'd like to see more of Diane Duane's writing and her Enterprise crew-folk: Harb Tanzer, Lia Burke, Naraht, etc.
Duane's Janice Kerasaurus was in
SCE: War Stories, set during the Dominion War, as a
veeeery old Starfleet officer. Also Terise Haleakala-LoBrutto, aka Arrhae, is mentioned as still being alive as of
Nemesis in the last book of the
Vulcan's Soul trilogy.
