In order to fix this, the code in sasgui/perspectives/fitting/ will need to be refactored so that whenever plugins_reset() is called, the entire list of standard models (available from sasmodels.sasview_models.MODELS) plus the entire list of plugins (available in self.stored_plugins) is scanned, creating a new self.struct_list with all the structure factor models.

The ModelManager.get_model_list() method uses self.struct_list to set the "Structure Factor" element of the model list dict, which it assigns to FitPanel.model_list_box in, which sends it to the FitPage via panel.populate_box() method when add_empty_page() is called. This calls self.initialize_combox() to trigger _populate_box() to append the items one after the other to the self.structurebox combobox.

The same code that triggers plugins_reset() needs to reset the structure box for all fit pages. This happens in Plugin.update_custom_combo() within Once the new struct_list construction code is done, it should just be a matter of introducing the following code into update_custom_combo:
