Feature Request - Create Circular Arc selection method for points

Currently to be able to use the tool one has to have a point layer before hand, this leads to double digitizing, you have to first create the points that define the arc in a point layer and later select them using the tool. I think it would be better if the tool could accept snapping points from other layers (lines, points, polygons) but also on screen digitizing, that is clic on point to define it. This is particularly useful when you are tracing imagery.

As it currently stands there is a lot of duplicated effort towards creating arcs and really time consuming once you need to do more than 2 or 3 arcs
