When updating a page in the main language tree, there should be a "Mark translations as outdated" checkbox. The checkbox is needed, for example, to correct a typo that does not affect the other translations. When you edit a translation, you should be able to uncheck the checkbox for that language to remove the notification.

Add a status label/badge like in confluence (A simple bootstrap label/badge which can contain a text). They are very useful to highlight a current status. Compared to the highlight feature they are also much better visable. A example is my attached image.

It might be hard to integrate, but it would be a killer feature that no other wiki offers. Perhaps you could use ShareDB: https://github.com/share/sharedb https://en.wikipedia.org/wiki/Operational_transformation

Currently when moving or renaming a page, all existing links point to the old page. The correct behaviour would be to update all links to the new page, either optional or explicit.

To be able to open images that are inserted on the page in a popup/modal window or in a FancyBox/Lightbox. Also, to have varius types of galleries, sliders and slideshows for the images.

It would be great to have an administration tool in "utilities > content" which would allow to list all pages containing broken links. The tool should be able at least to list broken links pointing to internal pages of the wiki instance. An advanced feature could be to list broken links that point to external pages. It would ease greatly the maintainance of the wiki and keeping it up to date. Thank you in advance

I need to add some content to the footer of the login page, and there seems to be no easy way to do it now

Although a wiki is a collection of pages, often they are organised in a tree structure. If you want to move a page that is at the top of a subtree and all pages below it, that is very cumbersome. Adding a "move tree" function would greatly simplify moving, or renaming, subtrees and keep consistency.

Save current state of the buffer when editing a page, so in case the page is closed or the browser crashes, the work is not lost. This would work better with a warning when the page has been changed since the time the draft was saved.

One of my goals is to not duplicate information, which includes creating "one-off" slide decks when the same information is on the wiki. It would be great to support something like Hacker Slides as an alternate way to render a wiki's markdown page when I need to present the page's content in a sequential fashion. This way, with a little extra content, the same wiki page could both be read like a document and presented as a series of slides.
