Add an option for the wiki start page to be "index by title"
Often in a project, a collection exists of wiki pages which are unrelated to each other. And there is no umbrella page with an overview of these pages. There might not even be a designated start or intro page for the wiki at all. The wiki might just be a collection of unrelated pages containing distinctive topics. So it would be very handy if the entry point (or start page) of a project's wiki could be an index of all wiki pages. Preferably sorted alphabetically and displayed hierarchically. This would relieve wiki editors from the task of creating (and maintaining) a start page themselves.
Actually, such an index already exists. It can be accessed for every project, via projects/project_id/wiki/index. You can also find a link to it in the sidebar of the wiki. However, it is currently not possible to set the start page of the wiki to this index. This should be made possible. Perhaps also make it an option to choose between index by title and index by date.
Unsatisfying workaround 1: redirect¶
Unsatisfying workaround 2: index of child pages¶
You could create a wiki page and set it as the start page. This page would use a macro to displays its child pages. The major drawback is that all wiki pages would have to be a descendant of this page. Also you would have to manually create this start page over and over again for each new project.
