A reset button to revert settings under 'Sample settings', 'Envelope / instrument settings' and 'Miscellaneous functions' to default values.
Because you need to save you're plugin settings before reloading the plugin (or else it's lost) and only changing the plugin preset doesn't reset wrapper settings.
Bonus: Add wrapper presets. (Not Channel states b.c. these also save / load containing plugins).
