You can click it in. So, you could have 4-way directions with touch and then a plus input with click.
Though he meant 5 buttons, assuming he wants to click all of them. That would be tricky. If you make the 4 only register on click, it couldn't separate a 5th input from them. Only if it's something like shift, then you could have shift+1, shift+2 etc on the pad.
Right, this matches my understanding. 4-way only, but I hope they add 5-way in a future patch. I think people will be using the d-pad mode with shift mode buttons as a workhorse.
You can still set doubletap as an input.
I didn't know this, kind of interesting, even if I imagine it will be less reliable than a click.
