I think I already complained in the past that the shortcut for the overlay being ALT+W is bad, as you press that combination regularly in some games with WASD control. I was happy to see when I ran into this problem again, that there is a new option to change this. My happiness was short live as there is only another fixed option ALT+`. First, I'm not even sure what character I should press, but after trying every button that seems likely I can say that it doesn't work on my keyboard layout. Why can't we have this setting fully customizable, when we can already set custom shortcuts for the mods. It doesn't make any sense.
Once again, I can't use the overlay because the fixed shortcuts for it are unusable.
