Using the GUI, the estimation output is overwritten in the Gretl assemblage in the Windows taskbar if an alternative specification is chosen, including estimation results , graphs of model fit and forecast . On the other hand ARIMA option (and for that matter OLS estimation) retains all model variant outputs and graphs for inspection and comparison.  While I realise the output, graphs et can be saved, this really is not necessary in the process of model selection where a visual inspection is more efficient and less time consuming.  Any chance this can be rectified?
