Minor petty fedi gripe: Adding a hashtag to a post after it's been published does not add the post to the hashtag listing. So if you want the post to be included in the hashtag listing it looks like you have to delete and publish again with the hashtag.

As someone who frequently thinks of relevant hashtags for Pixelfed posts after the fact this makes me irrationally angry. Have noticed the same behavior at Mastodon but don't hashtag as much there.
