[QGIS-Developer] Exploring the new node tool: questions and bugs(?)

the new node tool has an unofficial name : "click-click node tool".
The new behavior is to first click a node to select it and then click the
I was also surprised at start, loosing the very common click - drag -
release workflow was not natural to me, coming from Esri-Mapinfo world (a
long time ago now).
After using it in Martin's plugin prototype "CAD Node tool" I finally got
convinced that it is a lot more productive in fact, and allows to use all
the advanced digitizing options and modifiers.
The node panel is raised on demand using right click, this was annoying to
always have it before. In latest master, it indeed is broken, it just opens
and closes immediately.
It's true that the new behavior is more natural to CAD users than GIS at
start, but I think it's much more productive this way.
Double click is still here to create a node, or you can just click on the
centerline virtual node that appears when you hover the feature. (It's a
red cross rubber band)
Moving a segment is like before but still in clic-clic mode, not
There are also some other improvements asked by some users, and any
improvement or feedback is welcome:
- add a varying symbol to confirm what snapping type is made (segment /
node / vertex)
- add a better batch vertex selection method, allowing to select all
vertices between two selected vertices
- allow to have priorities for layer snapping
- add advanced option to let user explicitly choose which layer and feature
should be actually snapped to.
I think this change is a heavy new feature that will need to be advertised
and documented .
I'm even wondering if we shouldn't even change the node tooltip until 3.2
from "node tool" to "node tool /n new behavior, look check the doc!"
