The drivers currently available for the AW13 (and, I'm guessing, other 2015 and 2016 models) are inexplicably crippled. I know for a fact that the I2C touchpad installed in the 2015 AW13 is capable of detecting clicks and taps using both three and four fingers. Why is the option to customize the behavior of these hidden in Dell's drivers? Even the non-OEM Synaptics driver package hides them. If I install a Lenovo ClickPad driver, I'm able to customize three and four finger taps and clicks.

There doesn't appear to be a technological reason why these options are disabled - please add them to the next touchpad driver update! Three finger click to emulate middle click is a must-have in a laptop, and it's impossible to do that right now with Dell's drivers.
