Glad to see this was proposed and I see already a comment about the dynamic vertexes (geometry nodes) is present. I would like to add to the idea, as I see currently only an existing vertex is active for the delete action. So, the D key does nothing on dynamic vertexes, but they are active points in WME, as you can create a vertex/node at that spot. So the D key can be used at any such place on the segment to split it, rather than delete an existing node. No need to click and select with the mouse. The requirement to save will provide an easy confirmation mechanism. Once split, we can always adjust the spot, if needed.

The only thing I would add here concerns another proposals like the history for a split segment and most importantly - the segment travel data. But this is up to the devs to decide how to deal with. Of course, the best option would be to have the possibility to add a virtual node in cases where you need to split for speed limit needs, which was an internal Waze idea, as far as I remember.

Especially now that we have the ability to add a geometry node anywhere on a segment, if a right-click could change this to a cut tool rather than an add node it would be so easy. Thanks for listening.
