Can you give me a for instance? I was able to press start and access maps before just fine, now that button has been crammed in-between the face buttons and the huge map button. Guess which button I use more?
In Days Gone depending on which way you swipe you get directly to the Map, Inventory, Skills or Story missions, all which you can still get through the Menu but having direct shortcuts adds a little to the QOL of the game.
For me these redundant functions come at the expense of a better placed start button. It's a neat and not totally useless idea, but it hasn't proved it's worth to me at all in 7 years. People can give me a small handful of games that have even tried to use it. But like you said it's redundant anyway, this isn't necessary or game changing at all, it's superfluous and the sticks work just fine. To me it's an absolutely inessential peripheral that they crammed into their perfect controller.
I don't like a full screen, but something like this would be interesting. A touch button with lot of tiny holes to see a simplistic low resolution lcd or even diodes behind to show some information,
might be just a debug unit or it was a prototype that never made it. It would be cool if its a debug unit, but with that screen it should be wired only.
