Shift Points is a simple QGIS Python plugin used to modify point shapefiles where several point features have the same position. With the normal display, it is hard to see if several features overlap.
The Shift Points plugin moves such features in a circle around the "real" original position. As you can see this is very close to work of the "Point displacement" renderer in QGIS. But while renderer only works in render-time, this plugin creates new shapefile with shifted (displaced) features.More info can be found:
