Allow the craft to be rotated and translated at the same time. This could be easily implemented just by allowing I, j, k, l, u and o to work as transition controls and make docking a lot easier.
@118Industries after looking further into it further, it appears that there's only one set of controls for both "normal" movement and translation with a key to switch between the two. So I'm pretty sure you're right about having no choice but to switch between the two. I did notice that you can set two different keys to the same function, but that doesn't help if you still have to manually switch back and forth from translation mode.
And as far as mobile goes, one set of joysticks is bad enough... It takes up a huge amount of screen space, and covers(or gets covered by) other important displays/buttons which makes it really hard to do certain things(like flying a plane. I literally have to use the joystick to take off, lock my heading, turn off the joystick, open up the ag menu(it covers the joystick when opened or blocks my view if I move it), retract the landing gear, close the ag menu, turn joystick back on, unlock heading, and only then can I begin to fly the plane like normal. I realize I don't need to go through that exact process, but it's more like actually flying than just using the navball and heading lock). Two joysticks at the same time would make it nearly impossible to play the game, or at least not as enjoyable. I would personally prefer a "gyroscopic" control setup using the accelerometers in your device like a flight simulator to adjust your pitch/roll/yaw while translation mode is enabled since you could use both simultaneously without losing valuable screen space
@YaMomzBox420 I think you still have to switch between translation and standard controls even if you have them on different keybinds, but I haven't tried it. It could probably be added on mobile just with a second set of joysticks.
That wouldn't help mobile users very much(unless we have a Bluetooth keyboard) which is probably at least a major part of why the controls are the way they are. There might be some other reasons involving the actual coding of the game, but I don't really know. You do have a really good idea there since the control scheme you mentioned would greatly simplify the task of piloting a craft by hand, especially during docking.
Actually, thinking about it, can't you custom set up your hotkeys? Even on mobile, it has a settings menu for all your keyboard controls where you should be able to select a specific key for a specific function. I haven't really played around with it, so I don't know for sure if it's possible to set both controls individually at the same time or if they have to be the same buttons with a "switch" between the two modes
