Oh yes.
Also, it would be nice to have a button in the specify model dialogs

Better still: select variables from the main window via shift-click,

Excellent idea!

I like this: however, there's a syntax problem; not unsolvable, but a bit
annoying. At present, modtest has one optional argument (a scalar), mainly
used in a time-series context. Allowing for a list makes syntax parsing a
bit more complex. But then, a nice opportunity opens: how about replacing
"add" and "omit" with "modtest <list> --add" and
"modtest <list> --omit",
respctively? Clearly, this would be massively backward-incompatible, so
obviously it would be a 2.0 thing; still, in the meantime we could keep the
two.
I like this one too. It fixes the add/omit 'problem' -- as in what to do
with them. I wonder if a more flexible version of modtest that could take
more inputs would help? To maintain backward compatibility it would have
to have a new name -- definitely a version 2.0 thing, though. On the other
hand, it would be confusing trying to figure out which to use... so maybe
not....
