I have a customer who's exploring the possibility of migrating a community they currently maintain as a facebook group to a self-owned platform.
I've installed a Flarum server for them. Amazingly, I could find extensions for almost everything they needed. The main "show stopper" is that a discussion list (even with jordanjay29/flarum-ext-summaries and fof/discussion-thumbnail installed) doesn't look like a social-network feed: Entire post (perhaps collapsible) + latest several comments (+ additional comments collapsed).
Is there an extension that gives Flarum such a look?
If not, would anyone be interested in developing such an extension? How much would such development cost (ballpark figures)?
