Provide create file link for non-existent files
When there is a dead link in a Markdown file, clicking it leads to a 404 page (see example). It would be great if that 404 page could contain a link to create the file (optionally with a permission check beforehand).
This would also be more consistent to the Wiki behavior, where a non-existent page displays the form to create it.
Current workflow when landed on the 404 page is:
- copy the file name from URL or referencing file
- go to repository tree
New filefrom context menu
- enter file name
