Ability to pin a small marker with a text label ("70q soil", "Constantinople", "Jay Estate", etc) on a map made with cartography skill.
Right-clicking anywhere on opened map brings forth context menu with "Place pin" option. When chosen, it places a pin where mouse points and gives you an option to enter label.
Right-clicking on pin brings forth menu with "Remove pin" and "Label" (changes label). Alternatively, right clicking only gives you label window, and if the window is empty, pin is also removed.
New text label appears on mouse over a pin icon.
Pins with their labels are not copied when copying a map of same scale, BUT is copied when a smaller map is drawn onto a bigger one.
Sorry if it was discussed before, couldn`t find it in Ideas.
