I am glad to inform you that Gretl is gaining more ground in my country Nigeria nowadays. However, I will like to make few suggestions to add to its usefullness. 

I think there is a need to develop a special GUI for SVECM and to support both long and short run restrictions. If possible, it can be linked with the VECM output in order to fetched its estimates from the beta-alpha matrix. 

Moreover, I suggest that Gretl should be developed to handle DSGE modeling. 

I think my opinion makes senses and I wish to hear from the developers (Allin and others) soon. 

Regards. 

Timmy John.
