1) I'd like a controller without a pathetically short battery life (seriously, the DS4 is almost as pitiful in that department as the Wii U GamePad, and that had an entire friggin display built into it!)

2) Make the share/options buttons actually protrude from the controller, and make them slightly wider. They're annoying to press.

3) Shrink the touchpad. Seriously, most games only use it as a select button to begin with. It hogs a ton of room in the middle of controller and I almost never use it.

4) Shrink the lightbar, and allow us to push a button and turn it off. It's pointless, annoying in dark rooms, and is probably eating up energy that could be used to keep the stupid controller alive longer.

Otherwise, I really love the DS4. Aside from the forementioned issues, it's an incredibly comfortable controller with a great D-Pad, comfortable analog sticks, and wonderful triggers.
