Niggle: the vertical bar that separates column headings is missing from 2.0beta3. I can still drag the invisible column boundary to change the width of columns; just missing the visual clue that shows the column boundaries.

I saw it on Mac OS X 10.4. If you are seeing it on a different OS (or version) then it would be helpful if you could update the bug listing with the OS you use. Thanks.
