It is so awsome that you are adding new features and I would like to suggest improving space to fly!
I really dont like space to fly mode because you jump super high and fall slowly, its not as elegant or fluid as this solution:
You dont actually control yourself in mid air. you continue to go higher unwillingly. with the hack I linked to you are actually pausing in mid air!
I would also love to be able to control hotkeys, I want to determine that ALT is for speed hack instead of shift, because I use shift for evading.
keep making the hack better, it really is getting that way
