Tried that, if you Parent past MainHUD it doesn't do anything.
(If Parent refers to MainHUD.Player, and Parent.Parent refers to MainHUD, then Parent.Parent.Parent.Inventory should refer to Inventory, but doesn't.)
Nuts, you can't do math on things with 2 values (Size, for instance). I was hoping for a hotkey bank with scaling buttons.
Nor Boolean values. (1-true isn't false, sadly.) (EDIT: Use
! to invert true/false.)
Can't change the Opacity values of windows with eq2usescomwndcontrols="true", the Window Settings opacity value will instantly go back into effect. You can use Visible to show/hide the frame/titlebar/backdrop, though.
