hello!
i think there should be options in the overview docker where you are able to customize what it displays! for example, if you doing lineart you could toggle a setting to make it only show the lineart layer. this could let you see how your progress is coming along on your current layer only without having to toggle off all of the other layers, you can just glance over and see
another thing (i dont THINK this is already a thing but if it is i couldnt find it) would be an option to completely turn off saturation on the overview, this would help check values while coloring and rendering.
thanks for reading my request!
