[Qgis-user] After deleting points, attribute rows persist

[Bernhard Ströbl]

Maybe the node tool shouldn't be available when editing a point layer? 
Anything one may want to do with points can be done using the other 
tools (move, delete part). I was always wondering why it is there 
because AFAIU nodes are not individual features, they only exist as part 
of a line or polygon boundary, but points in a point layer are 
individual features themselves.
