Feature request: <null> in table view

[Raymond O'Donnell]

I find it really useful that, when you open a query window and enter a
select statement, null values show up explicitly as <NULL>.

However, you don't get this when opening a window ("View data...")
directly onto a table or a view, and it would be particularly useful
here. I'm currently rehabilitating an old database with lots of null
values across 90+ columns in one table alone, and trying to track them
down is a pain.
