It's no different than using any other button that forces you to let go of the analogue sticks. It is super easy dude. Unless you have issues pressing the d-pad, x, square, 0, triangle, start, select, or ps, you will be perfectly fine with the touchpad.
Except I only need one hand to touch the x square triangle buttons and can still use the analog not both dude. Not exactly mind blowing and you are not exactly thinking about it just blindly accepting it. Peace out. Dont feel like getting banned over someone that isnt thinking things clearly
