Rated 4 out of 5 stars
One thing missing from the old look is the Account column header label - 'Name' is what was there in the old TB2 - or maybe 'Account Name', or just 'Account' - but right now it is blank and looks funny. Fix this and its 5 stars.
@Edward Gelb - actually, I prefer this, otherwise the space to the right of the numbers is wasted.
I'd also like to see support added for showing the space taken up by a parent folder showing the total for all sub-folders - but this was NOT the behavior in Tbird 2, so I don't see this as a regression or bug, just a Feature Request.
Thanks for the extension Joey! Imho, this was a dumb decision by the Devs to remove this code and relegate it to the extension world.
