Swapping between tools and loosing health when doing so is frustrating for the group that I play with. Would it be possible to add a config option that enables/disables bonus health?

You can do that by editing the default datapack

You mean opening up the JAR and editing it correct? Just making sure as I saw no mentions of datapacks in other spots. Thanks for the response!

No you can create a separate datapack which overrides the default one.
