Wiki.js

Any possibility of adding multiple wikis within a single installation? Much like bookstack , it'd be great to have at least one extra level of organization (equivalent to "books" in bookstack).

During the installation process, the view can have a toggle to setup the guest user for a private or a public wiki, so there's no need to change the group rules for that later, unless that someone wants to public a portion of those pages or it's entirely.

I request that the LOGLEVEL parameter be created in the docker image so that it is possible to configure the loglevel in the config.yml file. Thank you.
