Feature request, circular nadir hole fill

[photographer]

The new fill feature is nice, but I prefer a circular fill, as most of the time, the tripod legs stick out of the polygonal sides, and a circle also hides the location of the corners of the seams.

The way it could work is to center the circle on the 0 degree nadir, measure the longest distance to the outermost transparent pixel from the center, and use this value as the radius of the circle for the fill.

Thanks

I concur with both the problem and your proposed solution. Even the possibility of leaving the nadir circle black would be an improvement on a polygon with protruding tripod legs.
