Well, you should have in mind i didn't read the config file about what i'm gonna say next. Once clarified that, those are my suggestions:

1. There should be an option to unable damage to mobs and players during non-fighting mode, because during pvp i noticed that people who doen't use the combat mode tend to win more fight that those one who uses it.

2. A config option to lock the 1°/3° person camera and a key to switch between them.

3. A less intrusive animation tweaks because it's incompatible with AI & animation mods (for example, it overrides the spider's AI & behavior from Spiders 2.0 mod)
