One of the reasons I sold my steam deck at launch and kept my Aya Neo 2021 was the steam decks lack of physical hot keys (not binds, dedicated programmable buttons). Having physical buttons for the escape key, on screen keyboard and task manager was simply too useful and important to me. I know it’s not an issue with steamOS and it’s moreso a windows thing but I wish valve would add physical hot keys to the steam deck.

Besides that, an extra usb-c port and hall effect joysticks would be a must on the next steam deck system for me.
