The scene/session version of the script now has no any limitation against the main script:
1) per-person data is saved/restores in the scene data including current preset values
2) the same behavior when disabled/enabled script/person
3) ShoeHelper removing ability
The scene version has not protection against main version applied on a person simultaneously, remember that if you use it as a session plugin.
It was a huge refactor so there are bugs could be introduced, please inform me if you found any.
