TL;DR
Add "personal_construction_radius_visualization" to Prototype/UtilitySprites and add the graphic "__core__/graphics/visualization-personal-construction-radius.png"What ?
I suggest that the sprite used for personal robotics equipment zones be separate from the one used for Roboport Construction zones.Currently when using a personal roboport inside of a larger construction zone it is visually unclear where your own personal construction zone is.
This is shown below with a personal zone (not to scale) and a roboport zone shown: Optimally something similar to the below would be possible: The way the current roboport construction zone and personal roboport construction zone sprite is defined is through Prototype/UtilitySprites/construction_radius_visualization and "__core__/graphics/visualization-construction-radius.png". My proposal is to have added a field called "personal_construction_radius_visualization" to Prototype/UtilitySprites and add the graphic "__core__/graphics/visualization-personal-construction-radius.png"
Why ?
This will hopefully add visual clarity to personal construction zones. And may even be fun (This is where I would show an image of Rick Astley as a personal roboport construction zone but the image of Rick I tried to used was larger that 11x11 pixels )Realistically this is a very niche thing that shouldn't add too much complexity to the game while adding a small amount of visual clarity and potentially a little fun.
