Would be nice to have a feature to rename a page, e.g. after a URL was published, bookmarked, but then changed. Automatic redirection to the original URL.
If in page foo you write [[Bar Baz]] and click the new link, the created page will be BarBaz.edit. Later, it will turn into barbaz.view.
For SEO, it would be best to separate words with hyphens or underscored. For consistency, they should be kept lowercased.
