I agree that SM is confusing, and I honestly dislike the "energy" system that caps sprint-jumping (which by the way is the main way I get around fast, since mounts usually lag too much to be usable).

There is also, honestly, no problem with the suggestion. I, too, would like to see 1.13 swimming in this mod, since updating is out of the question.

Unfortunately, though, Mevans has expressed that he doesn't know how to edit the code of Minecraft itself without the use of coremods (which he does not want to use). And SM only works with the animation API mod. Since Mevans has also expressed his dislike of using other mods to create his own, I just don't see an easy way to add better swimming.
