Short question: Is it possible to create issues for the gjs documenation and if so, where? I noticed that for example for the switch-page signal of the notebook here (https://gjs-docs.gnome.org/gtk40~4.0.3/gtk.notebook#signal-switch-page) has only two parameters, but I had to use a third one to get the index like specified here: https://developer.gnome.org/gtk4/stable/GtkNotebook.html#GtkNotebook-switch-page Or is this just a misunderstanding on my side and this is not the same? Thanks :)

You mean the last one (user_data)? https://developer.gnome.org/gtk4/stable/GtkNotebook.html#GtkNotebook-switch-page You can ask this question with pinging @ptomato here: https://matrix.to/#/#extensions:gnome.org
