More contrast when starting probes

I like this idea. I have a few thoughts.

I feel like such an overlay would have to toggle. That way, it doesn't ruin the look of the map except when it's useful. Perhaps it could be part of the economic scan thing?

Otherwise increasing the size/width/visability of the border line would be a good way to better show where explored space ends.

Yes, this was what I meant. When you click on the probe the overlay should toggle, so you can see, what you have already explored.

Better contrast of exploration-borders would be nice too
