sorting: I explained how gtk_tree_model_ref_node works to Federico today. As the best example of this is probably in GtkTreeModelSort, I ended up reading the code again. I had forgotten how conceptially clean the code Kris and I came up with there.
While doing this, I had the sudden desire to update its API docs. I’m not super happy with what I wrote, but it looks much better than before. It should help answer a lot of questions people have with that object, if nothing else.
It felt quite therapeutic to write docs. I should do this more often.
