Current way of circle generation y intuitive and suitable for most common cases, defining the zone where circles hit surface in toe and head of the slope.

But being able to make the circles pass through other zones would be great in other situacion.

It would be great to fix a rectangle in the interior of the terrain through that should be crossed by generated circles.

It would be great for testing circles to calculate the global factor of a pile or sheet. You could in that way test circles forced to pass near the toe of the sheet or pile more easily.

You could forced circles to cut surface between the limits and pass through a point in the (optional) grid you add under the pile/sheet.

Other improvement could be having other optimization method, that let you define one circle (passing under a sheet or wall) and let the program vary the circle parameters to search for a near circle that has a local miminum FOS.
