This is a long term desire from the users and it should be fulfilled with this PR.
It aims to solve the problem of losing the joystick connection when the standalone application (electron-version) window is minimized or completely obfuscated.
To solve this problem we need to access the joysticks via its HID interface. Different from the Gamepad API, the HID data is updated even when the window is not visible.
The biggest challenge is that, different from the Gamepad API, where there is a standardized access for buttons and axes, the HID state is completely different from one joystick to another. The HID buffer basically exposes the data as the manufacturer decided to, so we need to have dedicated mappings for each joystick, and we probably want to offer a UI that allows the user to map its own joystick as well.
My goal is to work on this PR in parallel during this quarter, and continue on it as a priority in the next one.
