Column order Rated 3 out of 5 stars

Very nice and useful tool.
I agree with Leon Simpson, that the column title should be "Sender name" and not "Display Name"
Now it seems, I have to restructure my address book in order to display lastname, firstname. But with this the display name is quoted. Why? Is this neccessary? Or are there other means to display last, firstname?
One bug: the column order of "Display Name" is not saved in Thunderbird 2.0.0.12. After restart it is always on the very right side of inbox.
Regards and thanks
