Add option to disregard keypresses in menus when selected menu option is not visible

[Edward Hart-Davis]

For example, I can have the 'Event Log' selected, while facing all the way down, without seeing it, at FOV 100, and I can press buttons to go into that menu, if I'm clumsy, without realizing where I'm going.

The last selected menu option at the top or bottom stays selected as you look past it - this is useful. Your FOV and aspect ratio is variable so there's no one-size solution for determining when something is off the screen, either. This doesn't need an enhancement... Just don't press buttons for no reason :)
