Question [Q] Switch hold home button and menu button functions

Hi

I bought galaxy s4 last month but I am not happy with functionality of the home and sensor buttons. In my opinion switch application (the list of all previously opened apps) is very important button and I am not happy to wait whole second holding down home button to get simple alt+tab feature. At all this big hardware button does not fit in the whole picture and its the biggest mistake of this phone. Now I cannot remove it but at least I want to use it as much as little I can. So I want to switch menu button and "hold home" buttons. Its far more sensible to make separate sensor button for switching app than use it for menu functionality. I didn't root my phone and I don't want to root it but if its needed to get rid of this stupidness I will make it. So is there any way to switch menu button and "hold home" button?

thx
