rob006 Justman10000 if you use flarum-extension type, Flarum will show it in the admin panel and look for specific files in the package folder, like migrations and extend.php. As long as the user does not attempt to enable it, it shouldn't crash the forum but if you try enabling such a non-extension then you might be unable to access the forum.
I think the library type is more appropriate for meta-packages.
