The immersion factor

I'm really enjoying the snips of voice "barks" when a contact pops up in the romulan storyline, even if they aren't reading off the whole text, it's a nice little touch.

I like how the little side tabs of dialogue with the character speaking come out in space too, the naussicans early on and thier leader transformed from a standard space kill 3 x mission to having some flavour and humor as my bridge officer reacted to the second attack.

I love the way these bridge officers come in as well, It's nice to see some story elements and personalities. I understand some people want to create their own crew, but I always felt that cryptic's unique boff's should have come with personalities and voice work and some personal missions. I'd love to see the breen, borg , reman and jem hadar bo's from the featured episodes have some of this as well one day.

I feel much more attached to my crew, and more engaged in the combat and action on screen when one of them pops up on the side and makes a remark, I even laughed out loud at the naussican pirate.

It would be cool one day to have dropdown menus for personality on boffs, like grumpy, prankster, honorable etc and a few voices to choose from.
then in combat or missions you could have triggers like on death or on critical that made them say something appropriate to those definitions.
