I know Rewind Mod was just recently added, and I already love it. Replay Mod has better camera control but Rewind gives you many more things to work with, which makes it better overall. However, other players’ POV looks pretty bad right now. They aren’t looking forward and often look down or to the side, which makes the POV feel weird and awkward
Personally im a Minecraft editor and I love experimenting with edits so fixing this would help me a lot and probably many others too.
