Is there some reason we can't jump after reaching 3000 meters useing the normal jump key like you are useing a wormhole? It does not make sense to have to go to the Nav screen to jump. If there is a way to do it let me know please. :-)

Yep. I suggested this before. I think they're going to implement it soon. The devs said they're planning to make it like that I think.

in the meantime, you can hit n and then j - very quick if you've preselected a destination.

What i'd like to see is watching the insector jump from inside the cockpit every now and then. The transition gives a sense of speed, but the speed would truly be felt if it were experienced from first-person perspective.

Agreed. But I think the system to system jump animations should be left in third person, just to add to the visual quality of the game. So first person only for sector warp drive.
