Mastodon (not sure if core, or Glitch-Soc as that runs the instance I'm on) has an extremely useful feature of "Delete and re-draft" being an option in the context menu for your own posts. It deletes your post and opens the composer pre-filled with the former post's content. This saves you a few taps/clicks/keystrokes if you spot a problem with a post and want to redo it.
