I.e. automatically pressing the stop+start buttons after each respawn packet.
Should probably be configurable per-server (e.g. more useful for minigames, less useful for survival).

If possible, I'd love for it to allow users to specify RegExp that stops/starts the recording.
One use case would be to properly cut the replay properly even if there are multiple worlds involved

i think it would be cool to also offer a manual option to do it with specific files, or maybe differ cases where a portal is used to travel to the Nether or End (or a mod portal if that's the case)
