When selecting perks at the start of an age, you are allowed to check the map, which is really handy before making a consequential decision. With that in mind, why can't you do the same when bargaining for settlements?
In this instance, I have no clue which settlement Kanchipuram is, or where it even is in relation to mine. If I could briefly view the map to see where it is and what other settlements are nearby, I could make a much more educated decision here.
Please add the "view map" button to this screen as well; it would make life significantly easier.
