They're weird with contributions and fixing old bugs as well, to the point community run patchsets make it a much better product...

See Betterbird for reference and their blog posts, it sheds some more light on aforementioned weirdness.

Also see other comment in this thread mentioning how you can't search for "wedding". A bug that is 14 years now.

At this point I'm really considering trialing one of those two vibe coded clients recently shown here on HN.
