New shiny bridge!
Which is also why there is a wide variety of bridge designs between even the same classes of starship. There were even theorised to be mission specific modules - for pure science work etc that could be swapped over for certain types of mission.
....a-ha! A-HAAA!!!! It's so SIMPLE now! I understand completely! Finally!
NOW I know why, during TOS and the TMP-era, the weapons were never, ever fired from one single station! Sometimes it would be the helm station. In the next episode, it's the nav station. One of the movies showed a dedicated "weapons station", but the very next movie had the weapons back at the nav station. And that's why - Starfleet kept installing new bridges every week.
I can imagine Kirk, sitting in his quarters, when Spock contacts him. "Captain, the new bridge has been installed and is now operational." "Thank you, Spock - by the way, where's the "fire" button THIS time?" I swear, if Star Trek VII had been a TMP-era movie, rather than a TNG movie, the weapons controls would've been on Uhura's panel.
