Two players asked for this in reviews — controlling the translator from a gamepad, emulator-style. Here it is, and not just for Xbox pads.
NEW: You can now assign controller buttons or combos (for example BACK+A, or SHARE plus another button on a DualShock) to any app action: translate once, clear the overlay, toggle auto mode, switch view, and more. Assignments are made in Settings, in the new Gamepad section, with a press-to-capture UI — press the buttons you want and they are recorded. Both XInput controllers (Xbox-style pads) and HID controllers such as the DualShock 4 are supported, and the settings screen shows every controller it currently detects. Gamepad assignments work alongside your keyboard hotkeys. Nothing is assigned by default, and with no assignments the app runs exactly as before, with zero extra overhead.
NOTE: Combos are recommended over single buttons so normal gameplay does not trigger the translator by accident — the settings screen warns you about conflicting assignments. One known rough edge: buttons on HID controllers such as the DualShock currently show up under generic names (B1, B2, and so on) in the settings screen. Assignments work fine, but reading them back is not intuitive yet — a coming update will show what each assignment actually is in a clearer, controller-specific way. And if your controller does not appear in the detected list, please tell us the model on the community hub; controller hardware varies a lot, and real reports are how support grows.
