Interesting thanks for sharing it. Your board is a rectangle, so why you don’t flip the board 90 degrees to make it use all the display area? Actually your way is better to have this compound view with the schematics.
That is the orientation that I will be installing the board into bigger device and later debugging it. It helps to keep the board same way in pcbnew so that my mental cache of component placement is not invalidated. Ultimately just matter of preference.
I do use high contrast mode on occasion but for laying out tracks if it’s just 2 layer board I don’t bother. Red/green contrast is good enough to visually differentiate layers. I declutter the view by turning off unnecessary layers and it’s enough for me.
