Open any of the queries

Now ask yourself "How would I create these using the Query Designer?"

The situation is that you can not - if you added the persons table twice the
designer would create "persons" and "persons_1". There is no support for
actually setting the alias for the tables as there is for columns,

You could switch the designer off and then in the SQL view change the table
aliases, but by the time the query is complicated enough that it is a problem,
this becomes a problem.

There seems three obvious ways to add this enhacnement:

One support a Find & Replace function when in SQL view mode.
Two add a popup menu for the table objects with "Rename" or "Alias"
Three support in-place editing of the table object name.

Of course a combination of One and Three would be real nice.
