the mine placing circle

you know that circle when you build something? that indicates its size and where it should be going? they also exist for mines and I would appreciate it if there the circle was approximately the area that the minefield would later encompass. that way we can place them a bit more precisely and we can better judge what area we are about to cover, even with the randomness of the actual placing in mind. not a huge thing, but I think it'd help.
