Well, I just went through the thread you indicated, turns out both threads were talking about the same issue, and you were suggesting to add a hotkey function to toggle between melee/range mode while I was suggesting making the skill icon automaticly changed(flipped) to the one corresponding to the currently equipped weapon's type.
I think automaticly changes would be more convenient but anyway, I got a more mature idea now, please check if you were interested:
The thread I mentioned this new idea
