My previous comment #13 about creating a parameter class for the "undo fit" functionality is not as practical as I thought at the beginning. The parameters are already inizialized in the lmfit.Parameters.parameter classe and you also need the presets for the GUI.
So here I added a history_manager() and one_step_back_in_params_history() methods which create a list self.parameter_history_list and handle the history of the fits.
Notice:
At the moment after pressing "undo Fit" button the parameters/presets are set to the previous value and it is fit again, because the evaluation method doesn't work for me, better said I didn't test it enough.
