There doesn't seem to be a general "suggestion" thread, and most of these I'm assuming I'm just adding my voice to the choir.
HUD:
Could you add a bit more contrast to the component damage icons? For a more complicated suggestion, maybe make an actual static HUD for the engineer that shows the component damage. A cool-idea-but-never-going-to-happen would be to add a row of off/amber/red lights to the helm for the captain instead of icons. I know you're supposed to look around to see whats broken, but it's a bit counter intuitive when you have to look down at something dark to see whats broken instead of at the entire ship.
Commands:
I don't use a mic, and the audibles are awesomely intuitive! Could you add a few more, like "Aye/No" or "Hold!/Fire!" "Aye/No" could even be quick responses once someone uses an audible. Again, a cool-idea-but-never-going-to-happen could be to add flags to your ship for ship-to-ship communication, even if it was just showing the f1-f3 commands to the other ship
Helm:
Sometimes the helm interactive is too small, so if I have to jump off and back on quickly I don't get the prompt and sidestep off the ship, I seem to get the same thing if I'm too close/inside the guns.
priority for helm/guns:
It may have been a glitch because we weren't able to reproduce it, but as a pilot, when my engineer was using the helm I was able to take it from them, and when I was using the guns, my gunner was able to take it from me, If this isn't a thing, it should be.
Rangefinder: Am I supposed to be able to use the rangefinder while piloting a ship? It's been 50/50 on if it does or doesn't work while on the wheel. I know it only works with spotted ships so I know that's not the problem.
I love the sound/music! Especially the quiet at the beginning of a match when everyone is running to their posts. In the same way there is a different sound with engines in forward and reverse, could you add a start-up sputter from off to on? Hearing the sound of other ships would be awesome as well.
Very interesting way of handling joining games, where you're in game immediately and then load in assets over the next few seconds
