Currently, namespace is displayed as a prefix in the title.
It is problematic because of the following points:
- Readers have to be able to distinguish the real page title (without the prefix (example in a user page), or including it in a different way (“Help about link” is friendlier than “Help:Link”; “Strasbourg Portal” is friendlier than “Portal:Strasbourg”)).
- They also need to better understand if they are reading an article or a meta-page. See for example T62973: Make Draft namespace visually distinct from articles.
So, I think we should think about a design where the namespace would be more visible, but not as a title prefix.
However, the namespace prefix indication is useful for editors who want to link toward the page, especially when they just have to copy-paste it.
→Extending T18691 to level 1 titles could solve this question.
This issue is especially understandable on multi-language wiki: as a translator, I never know if I should translate the namespace, the title or both.
