We need to work on a line layer where some features are closed and some are open. The closed features need to be closed perfectly, so that the first and the last point of the polyline perfectly match. In Kosmo GIS this can be achieved with right-mouseclick->close trace, in GvSIG also with right-mouseclick->close polyline (or simply with a keyboard entry "C"). I could not find a comparable functionality in QGIS. E.g. snapping to itself would be OK, but it seems not to work on features that are in the process of being created. Only if a feature is already added to the dataset, it becomes "snappable". Or am I missing something obvious?
Note that to divide the features between polygon and line layers is not an option for us. We need them to be on the same layer with the geometry type = line.
