A new tool ("Move feature part") would eliminate the need for overloading the "Vertex Tool". The "Vertex Tool" would then be used only for modifying the shape of lines (including polygon outlines). Overloading the vertex tool may be convenient for many users and perhaps developers, but will probably be confusing for most users (even if it is renamed to "Vertex / Point Tool"). So overloading should be avoided.I don't really see the issue here -- the "move" and "delete" tools work with points, just like they do with other geometries. So you're free to use these to modify point features. Why do we need to restrict the vertex tool and prevent using it for points?Nyall I agree. I would not want to see different behavior for points vs. vertices.
A side note: To raise the awareness of the distinction between multi and non-multi geometry layers, could it be an idea to indicate that a layer is a multi-geometry layer in the Layers panel. Either by adding a multi-symbol, or by making new symbols for multi-points, multi-lines and multi-polygons.

On multi point layers, I was thinking of each part being composed of a single node, so I wasn't thinking of "either a node or a point" but both. With this concept in mind, the whole set of available tools works fine and predictable for me. Moving parts is supported now via the node tool by selecting all nodes of a part. It's also possible to delete a part on a multiline/multipolygon layer with the node tool. So also with respect to this it doesn't do anything special for point layers. I can see, that it may lead to confusion sometimes as described in the original email here. I am not able to say how often this happens in comparison to how often the node tool is used consciously. The node tool even gives a hint on the message bar, that "the geometry has been cleared, please use the add part tool to set the geometry for this feature". So it's trying to not be too obscure. Maybe the whole confusion can be ironed out by polishing this text a bit? Considering the separate tool for moving parts of multi-geometries, I agree it sounds like a valid tool to have, but I am a bit concerned of the clutter to benefit ratio. Does anyone have an idea how often this would be useful in reality? Thanks Matthias On 1/8/19 9:02 AM, Havard Tveite wrote:I agree that disabling the vertex tool for point layers is a good idea.

Move single point in a multi-point layer: There is no option to move a part in a multi-line or multi-polygon layer either (or I am not aware of it). Why is it different for multi-point? If there is a need to move parts in a multi-* layer, a dedicated tool should be established IMHO covering all cases. Do not misunderstand me, I really do not bother but I started thinking about the tool's behaviour for point layers during this thread and IMHO the behaviour is not consistent: 1) the tool is called _node_ but it works on _points_, too 2) It can be used to move/delete single point geometries or parts of multi-points, but it cannot be used to move parts when editing lines or polygons (neither single nor multi), furthermore for deleting parts there is another tool that does exactly the same.

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.
