Well, the keyboard control scheme has the no-auto-brake behavior and I like that. But I find it annoying that the camera is locked to the ship, meaning that if I look on the left and want to go there, I need to turn the ship left with the keyboard AND turn the mouse right to keep aiming where I want to go. Moreover If found it difficult to dock somewhere because there is no aiming marker and I don't really know if the ship is actually oriented correctly.
After a few minutes I ended up using keyboard control, and switching to mouse control when I wanted to either precisely aim for a direction or for docking or mining or combat.
And after maybe an hour later, I gave up switching (too complicated) and kept moving in mouse control mode half the time with Ctrl+W+Space which is a bit tiring (I think I'll try switching Tab and Ctrl in the bindings).
So in conclusion, I still want to control the ship by mouse. It's working great this way. I would like to disable the autobrake like in keyboard control scheme, and last but not least, I would still very very much like to be able to reverse the Left Control key behavior or maybe just making it a toggle.
Anyway, Thanks for your quick reply Koonschi :)
