• Save presets for various body types to quickly switch between fitting configurations.
• Use descriptive names for presets to easily identify their purpose.

Limitations:

• Presets are not transferable between different Blender projects or installations.
• They do not affect the actual geometry or modifier stack of objects, only the addon's parameters.

Tips:

• After loading a preset, you may need to reapply the fitting modifiers to see the changes.
• Presets can be a starting point; feel free to fine-tune parameters after loading for specific cases.
