Comment 3 for bug 1730752

I like it! It bears further testing, but I'm also not seeing the problems I noted in bug 1728952 when I was testing this code.

I have a couple of follow-up comments:
- When I columns is set to be visible, it continues to display in the manage columns interface lower in the order. I think most users would expect visible columns to display right at the top since they appear to display first. It also makes it easier to reorder those columns among the other visible columns. Bill and I discussed the possibility to add a 'move visible columns' to the top so that the user could force them to sort to the top.

- When moving a column, the column header highlights in green so that the user can see which column they are working with. When the user closes the manage columns interface, the highlighting should be removed.

Thanks Bill!
