A big criticism I have of Flarum is finding extensions and needing to install them via composer manually. This is great for people that prefer that approach, but can be a little advanced for casual forum admins out there.
I propose a page in the admin panel to see the most popular extensions and a button to quickly install them, like an Extension Library of sorts. It could help with new admins to get the best extensions they want without needing too much terminal experience or root access. Some forum staff have moderators that don't necessarily have root access but can control stuff like extensions and whatnot for a forum.
Plus it would just be more convenient all around. Of course, this would not remove the ability to use composer or how they are installed currently.
