Lock screen function actually locks physical button

I already sent a feature request with a full set of requirements to improve the screen lock feature.

I really hate the full lock, which makes no sense, as you said.
I just want the screen to be locked and it should immediately unlock, when a button is pressed. And of course the function of the button should be executed.

When the screen is locked and I touch it (the screen - not a button), then there should be a less intrusive way of signaling that the screen is locked. Maybe a red or orange ring, which does not block the view.
