[Qgis-user] How to transform a selected multipart feature into singlepart features during a edit session in QGIS?

[Alexandre Neto]

There are several questions and respective answers for how to make a
multipart features Layer into a singlepart features one using QGIS:

   - How to break a single polygon into multiple
polys?<http://gis.stackexchange.com/questions/27825/how-to-break-a-single-polygon-into-multiple-polys>
   - How to split non-contiguous feature in
QGIS?<http://gis.stackexchange.com/questions/23377/how-to-split-non-contiguous-feature-in-qgis>

But all the solutions I saw, creates a entirely new layer and would
transform ALL the multipart geometries into single ones.

So the questions is, how could one, during an edit session,
*selectively* transform
a multipart feature into a singlepart feature, without the need to create a
new layer?

I saw a ticket <http://trac.osgeo.org/qgis/ticket/3278> for this but it
seems to have been misunderstood.

It would be the opposite to the "merge selected features" tool, and similar
to explode<http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Merging_and_separating_features>
in
ArcGIS.

Is there any plugin doing this? How could this be done using the python
console?
