Does anyone know how to change the ‘Background’ of the Layouts window?
In this screenshot, I Floated my Layouts to better manage the interface (corners marked in red pen).
Unfortunately the Floating viewport does not pickup the Border Color from the Appearance>Colors menu (circled in blue pen).
It is easy to see how the backgrounds of the fixed and floated viewports blend together (Floating background where red squiggles are).
Does anyone have an idea to improve the contrast between floating and fixed backgrounds?
BTW: It would be great to change the thickness of the border line; this could also improve contrast.
