When playing with mouse and keyboard, this game has E to accept and Esc to say no... yet in the station menus for bying equipment and others, there's a duplicate yes/no via Y & N.
This is completely redundant and because the normal E and Esc keys DON'T work alongside those, it is a bit irritating to buy things.... every single time.

Devs please get rid of the extra Y/N keys...

I know, what you mean, it's a very bit irritating.

But, ... what I really find disturbing, not to say 'very annoying', is the common use of the Button "E" for Tractor Beam, Warp Engaging and Warp Pairing.
It's been several times now, that I did escort missions and every second time, I leave the mission area by accident, because when I pushed E long enough, it did not only use the tractor beam, but engages my warp engine.
This on first sight very smart looking feature of holding the "E" button pressed, is just stupid in the end. Why do I have to gather all the cargo packages one by one and every time wait this eternity until the circle runs fully around the E button...

That and the save system, which is ridiculously limited, are the only two things so far, that were really bothering me. Rest of it is a pretty cool spaceship game 8)

Maybe post that here http://steamcommunity.com/app/290300/discussions/1/

The devs should read this forum too!
Though if you want to copy-paste it there, go ahead.
