A Flarum extension. Adds a reply to see BBCODE.
Note that it only works for the main post (the start post of a discussion) because I don't think it makes sense to ask people replying to a comment post to see it's content. This BBCode will be replaced by div in comment posts.
When creating/editing a post, you can simply use the [reply] BBCode to make it hidden to other users until they've replied.

install manually with composer:
composer require littlecxm/flarum-reply-to-see:*
