Dear team,
If I (correctly) understood your messages, you are thinking that the
screenshots are from a real implementation of the proposed GUI.
Unfortunately they aren't. I made them using the "graphic editor
magic". I'm sorry if I led you to this missunderstanding.
I would love to know how to use some IDE (like Gnome Builder) to
create a real skeleton for Gretl's GUI.
Anyway, thanks a lot for your feedbacks!
Um abraço,
Henrique
