As part of the general tidy-up of the GUI, I'm wondering about the model dialogs where two sets of variables may be selected, for example TSLS (Independent variables and Instruments), VAR and VECM (Endogenous variables and Exogenous variables). For "historic" reasons connected with the original design of the model dialog, it was easier to place the "primary" selection (that is, Independent variables in TSLS, Endogenous variables in VAR and VECM) in the lower right position. However, I think it might be more intuitive for new users if the primary selection were above. Agreement or disagreement? Allin.
