Just a suggestion coming from a typical player.
I have accidently hit "N" far too many times to be have the game "freeze" till it pops up the GUI.
Have you thought about adding a SHFT or CTRL combo with the "N"?
I feel like my keyboard has become a minefield of bad keys to press and because of how long the GUI takes to pop-up, this one is a biggie on my list.
Just a suggestion and to get your thoughts...
Great mod!
