This is a good opportunity to be more specific about which faces are included. Going back to the devtalk thread, the behavior we chose deserves a bit of explanation IMO. Likewise with the fact that only the previous corner is used, not the next. That should be mentioned at least. Though if you're up for making some sort of diagram, that would be great too!

Yeah, a bit more explanation would definetly help in understanding the node better.

What do you think about this description?
The Corners of Edge node retrieves face corners connected to each edge in a mesh.
The node first gathers a list of the first corner, in winding order, of all faces connected to the edge.
It's important to note that the node only returns the first corner connected to the edge.
By offsetting the index by 1, you can then get the other connected corner to the edge per face.
That list is then sorted based on the values of the Sort Weight input.
The Total output is the number of connected faces/corners, and the Corner Index
output is one of those corners, chosen with the Sort Index input.

According to the diagram: I iam not entirely sure whats the best way to intergrate explanation pictures in the docs. But I created some tests, inspirered by the ones, I did for the devtalk proposial. I prefer the grease pencil one (1) more, because it looks familiar to blenders UI:

Yeah, that's definitely helpful! I like the grease pencil styled one too. I wonder if using some mesh for some things like the circles would help avoid the hand drawn look though.

gathers a list of the first corner, in winding order, of all faces connected

"in winding order" isn't quite right here, since that refers to the sorting of corners around a face.

By offsetting the index by 1

Might be nice to mention (link) the "Offset Corner In Face" node here, since just adding one to the corner index might end up in a different face.

New Version: https://ibb.co/5cVChYs

"in winding order" isn't quite right here, since that refers to the sorting of corners around a face.

Maybe a better description, but i find the naming very difficult to be precise:

The node first gathers a list of face corners which are connected to the edges.
It's important to note, that the list only has one corner per face.
Offsetting the index inside the face by 1 using the :doc:Offset Corners in Face </modeling/geometry_nodes/mesh/topology/offset_corner_in_face> returns the other corner, of the connected face to the edge.

Might be nice to mention (link) the "Offset Corner In Face" node here, since just adding one to the corner index might end up in a different face.

Yep, I'll be doing that with the next commit

That sounds great! And the image looks great too.

Small thing: there's no need for the comma after "It's important to note".

Great!
Corrected it.

Do you have a tip on how I can best intergrade the image to comply with the docs? Do you know an example in the docs where a extra explanation image was added?

The extrude node is the most recent one I worked on. Other geometry nodes have an "Examples" section at the bottom. That's not really an example though, so it's probably fine if it goes in the first section before the "Inputs".

The name, along with "node" should be filled in automatically.
