I think we need to get rid of the "undefined" pseudo-type. I would like
to change the "Add column" menu item to show a dialog with a text box to
enter the name of the column and a combobox to choose the type (and
precision too in case of varchar and numeric type).

Well, I also think we should get rid of them. Every action should start
within the contextual menu. No Add or Delete button. And I don't really
like the "double click" to rename an object. We should use the
contextual menu once again

Actually, it's the end of the GSoC. I think Luis still wants to work on
it, and I really hope so.

Yes, that would be best. The "play" button is the execute button on the
Query Tool. Quite confusing.

We'll probably have to get rid of the notebook and have two panes, one
to draw the schema, one to see the SQL. They can both have a toolbar. On
the draw pane, we could have load, save, sql buttons. On the SQL pane,
we could have save, run, open query tool.

Yeah, could be possible.

The last item we should not forget is a reverse engineer button. I've
read some parts of the code Luis wrote, and I think it should be pretty
easy to do. AFAICT, it's a one day job, considering all the foundations
built by Luis.
