Mofify in call menu

Anyone use an app that replaces the in-call menu with something a little more useful? I feel like I can do anything on my phone other than use it to call other people. Whenever the screen decides I've pulled my phone away from my face (which usually I haven't), the screen lights up and my ear brushes either mute, or opens some kind of dialing interface which mutes me to the person I'm talking to. This happens about twice a minute and it makes phone calls practically unbearable.
