If you want something not to be forgotten, file a bug.

Well, I don't have a good sense of which way this should go -
most of the time, you'd probably just make the expander column
not reorderable.

But that being said, my gut feeling is having it fixed makes more
sense, and in fact, if the expander column was always fixed to the
first column, that would probably meet 99% of people's expectations.

But file a bug, and Jonathan can decide whether to change it
or close the bug as WONTFIX.

Data about how other toolkits handle this could be interesting.

This is just a known bug. (Though except for the first and last
column, unreorderable doesn't really make sense)
