Please bring the control mapping back up to the level it was in x3.

[imanitu209]

As of now there are several issues in x4 that are step backwards compared to x3.
1) Modifier like Shift key with gamepad buttons (or one of gamepad's own buttons);
2) Hold button/long press;
3) Remapping menu controls like up-down-left-righ, page up/down etc.;
4) Modifier key as a separate input without losing its keybinds. Like for example inverse throttle would be useful to have on shift or fire on control.

The last one is probably more of a hassle to implement so you can just skip if it's too difficult.
