iD editor lines and areas
![alt text][1]The recent question on islands in a river highlighted a problem. The mapper had spent time and care drawing riverbanks as lines and an island, but as the riverbanks were not closed polygons it was not correct. Without using either Potlatch2 or JOSM is it possible to change lines into an area using iD and without wasting the lines and starting again.
i just tried what you said Ed and it still doesn't offer area features, only line ones.
