@noellabo Thanks! There's no hurry. I saw your PR on tootsuite/mastodon and your commits on Fedibird so I am trying to find bugs to improve the code quality.
There's a minor issue:
Circle posts are not displayed in Home Timeline. Is it an intended behavior?

@dmonad With Fedibird, I am trying a commit that regards limited (circle) as direct, but that is the effect. Not intended. I'll revert in the next update.

As explained in the PR, getting the circle reply tree to work with fediverse is a bit complicated. But Mastodon wants to aim for that, so I will work towards it.
