So for any users of the new rmbp with force touch chime in on this. On the system preferences trackpad setting, there is an option right above the force touch sensitivity setting that says silent clicking. Does anyone know what this does? Unfortunately, I am at work right now and can't post a screencap of it but turning it on and off resulted in no discernible change. Besides that, are there any new features involving force touch in El Cap. I know they opened up the API for devs to use on websites but other than that..
