When Qgis deletes features, they are kept on disk (see http://www.gdal.org/drv_shapefile.html). Unless files are "saved as", to force repack , MW5 displays those deleted features. It would be necessary to avoid that.

It seems that deleted features are flagged with 2Ah preceding each record if deleted link it would be nice to have a .deleted property for each feature.
