A problem I am seeing with the current measurement widgets is that they do not permit the line or polygon to be adjustable. For example, suppose I draw a polygon for the area measurement, then find I have to make some adjustments to the polygon (e.g. extent parts of it). With the current tool, I have to redo the poly, which can be a pain if it is complex. Same for the line if doing a distance measurement.
It would be good to have an enhanced measurement tool which would allow you to create or delete vertices of the line or edges of the polygon, and report the area accordingly. If there is such a widget I would be very interested in it.
