You can always use pothole markup to customize a title. The way the current system works is not something we can change within the scope of the database design. The 2.0 revamp that's going to start development after we get this redesign working fully will have an entirely new article mechanism that's going to support custom titles per-article, not per-title.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"In the specific case of Justin Time (or any case in which the only difference is capitalization or spacing), curly brackets can give you the title you want without resorting to a pothole, like so: ''WesternAnimation/{{Justin Time}}'' renders as Just in Time

Alright, well, I suppose that works for Justin Time (although still doesn't fix it displaying on the page) itself. Though I tested it before and it doesn't work for getting rid of that accent on Clementine. Ah well. If it's something that's going to be supported in 2.0, I guess that's good enough for now.

I brought this up once before and was told that it was a minor issue. However, it still bugs me and it is a wishlist thing of mine, so I'm mentioning it here. It used to be that when you did a custom title, you had to do it for each subpage, which wasn't necessarily ideal. Now, you just submit one custom title and it populates to all the subpages. Less hassle, but unfortunately it's also a "one size fits all" approach, which sometimes causes problems. For example, Clémentine, the animated series should be displayed with accent mark and is. However, I recently created a page for the children's book series Clementine which has nothing to do with the animated series, but is still forced to display the annoying accent mark, like so - Clémentine due to the one-size-fits-all approach. Another example - Just in Time. The animated seriess is a Pun-Based Title, Justin Time, but instead we get Just in Time.
