I want to resize my windows to not be blocked by MacOS's notifications, which are on the right side of the screen and 346 pixels in width.
I also want this to work regardless of my screen resolution (if I change my monitor resolution).
Fortunately, the notifications size is always 346 pixels.
However, in Custom Move/Resize Window, the options to size the width only show the
Absolute: new width x px
Relative to screen: new width x %
So I need to use Absolute.
How do I set the Absolute to screen size -346 px?
