It's been asked a few times but the answer is most likely no, at least in any close future.
May be as a backburner after all content is out OR with some of the content packs.
P.S. I'm not a developer. I just keep up to date with HK stuff.
Ah, I see. See how much you do for them so people are thinking you are a dev/piblisher. Thank you for your reply anyway. Even though I am a bit disappointed and actually surprised how such an easy to implement and for many people useful feature could be put on the "maybe" list. But that is something I would have to ask the devs and since you are not one of them I highly doubt that you could answer this question as well. Luckily there are rebinding tools like GlovePie and autokotkey on the market but the devs should be aware that it always leaves a sour taste if I have to use one of those just because the devs would not implement such BASIC feature. So of course this will influence my review I am about to write when I've finished the game.
