I got here an example for that what i mean now:
When i am playing in The Lost Tomb, i am much changing between knife and other weapons. When you dont have chainshaw, you just need to press the key once to activate knife. Wehn you will get a chainshaw, you need to click this key twice, thats boring for me, and because of that i found cool thing. In PlayerX.ctl i found, that there's possible to select knife by just clicking once the knife button, when you got chainshaw too.
But thats not enough, you can even split grenades from rocket launcher.
Thats cool featuer.
I got this file, so if someone want to have his own file. PM me, and i will create it.
That what i mean is everyone will want to have different. One grenades splited from rockets, second chainshaw from knife, third single shotty from double etc etc.
