Wiki.js

As an additional layer of security for embedding iFrames, allow the user to specify a list of domains from which to allow iFrame display and only allow iFrames to be rendered if they are sourced from the list of allowed sources.

The beta version won't run properly with HTTP proxies (example: no language file found, even if HTTP proxies are set up on the linux system level). It would be great to support HTTP proxies (system ENV defined, or using a dedicated wiki-js configuration)

PrismJS supports many languages ( https://prismjs.com/#supported-languages ) so why are only a few listed in the CKEditor for Code Blocks?

This would make life a lot easier instead of having to use spaces. Would also be a major help for lists. https://ckeditor.com/docs/ckeditor5/latest/features/indent.html

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.

Multiple h1 tags on the same page is not good for SEO. I feel like the page title should be the h1 and the content of the page should not contain any h1 tags. I like the current style of the h1 tags so I can't simply use ## instead of #. That would also be confusing for markdown formatting

ability to use different block quote styles in the visual editor (like in the markdown one) with the ability to also define custom ones. Css for the custom ones can be defined in theme settings or per-page css.

Add a feature to tag/mention other users of this wiki in native comments (e.g. ' Hi, @AndrewK') with autocomplete suggestions. The tagged user should receive either an email notification or a notification in the user area in the wiki itself.

When a user created or edited a page, it wont publish right away, rather have a admin or higher lever user to approve the modification, then publish.

Ability to delete folders in the Image / File Manager.
