A simple modify function where you would be able to directly edit the face to make it convex or concave.
Similar to the Direct and the Thicken/Offset function but here you would be able to make a bend in there.
Should be nice to be able to choose between the edges of the face. This way you would be able to make a simple convex/concave shape between two edges of the face or choose for a full rounded shape with (for example) 4 edges of a cube.
A simple tool to safe some time.
