Hi, I think I can handle this one ;)

What issue are you trying to solve ? Because last time I used it long press and triple press worked ok ... did you have issues with the long press duration ? (It was initially set to 5s ...)

I'm ok for the usb detection ...

There is another issue you can look at since you're at it, when powering off, if the button stays pressed the device will just reboot ... its ok with the sound because we know when to release button but not without sound.

It would be great if you could handle the btn release ... my idea was simply to light the led in power off and wait for the button to be released before actually calling sd_power_off (edit: this would solve #560)

edit : also we usually do the commits to the dev branch instead of main
