Thanks a lot! Everything works now.

One last question, the autosave options only apply when the entire interface is reloaded or if reopen moi3d

I call reload by method onchange="moi.ui.theme = value;"

This is fundamentally wrong, because it changes the theme of the interface, but reloads moi3d and applies the autosave settings.
I tried everything I could, and only this helped.

How to properly reload the interface without changing the theme.
