With the trackpad on my 2013 MacBook Pro using macOS, I use my middle finger for navigation and forefinger to tap. In this scenario, it is unnecessary for me to lift my middle finger to tap.
With Ubuntu 20.04 (Gnome 3.38) installed on the same machine, I must lift all fingers to execute a tap.
a) What methods are available to allow Ubuntu/PopOS to mimic macOS' behavior.
b) Is this typical Linux behavior or is this Trackpad-specific? (I don't have another touchpad to test)
