You can now decide if you want the horizontal format or vertical format. horizontal is the new default format, vertical is considered a legacy format.
It's in the "Edit Profile" bottom option in the
UserCP.
While I agree, vertical is much better on the wide-format... I am preparing to do away with the current wide format in favor a thinner view. I hate having two themes to support and so I just decided it was best to go thinner.
(see I listen)
Anyhow, obviously, some folks will be upset at this, but whatever. Down the road maybe run two. But not now.
