Add the possibility to perform a difference operation from two polygons that stay in the same layer, with a similar behavior of the merge tools.

I don't think that this refers to the geoprocessing operation, as it is already possible to choose the same input layer for a difference operation.
I thin that this refers to the advanced editing toolbar, where the user could choose two polgyons and using them for a difference operation, as it is said, in a similar way as the "merge selected features" tools work. It is not exactly a digitizing operation, but also the "merge selected features" is not.
Am I right?
doing spatial operations that involve more than 1 input, with ogr2ogr in processing, will be possible when the support for multiple inputs (using virtual vectors) will be added.

Hi More generally I have users askling for interactive tools inside the edited layer with classical intersect / buffer / difference tools. We had this in Mapinfo, and that allows a faster editing workflow. That need to introduce a concept of target feature(s) and source objects.
