Show all hotspots from gamepad

Hi. Thank you for such a great game. I am replaying it for the second time.
Now on nintendo switch and it is perfect in handheld.

But there is one thing that would be nice to have additionally:
highlight all hotspots by pressing gamepad button (while playing in stationary switch mode)

I perfectly understand, that the game is all set and polished and published, but can we hope for a such small update?

That’s IMHO unlikely, especially when there is only one small thing to change and nothing else justifying an update.

But now I do wonder… does the Switch version support keyboard hotkeys?
