Ok, I edited line 177 in inc-features.php to read colspan="$columns" and that fixed the title only going 1/3 across.
But I still need to get rid of the stacked effect (it doesn't appear in my PP install, so why here?). And the collapse button is still reversed.
Also, I have more than one PP license and installation, is there any way to have more than one "featured" box? I tried repeating what I just did and adding the new line to index.php but it gave a bunch of previously declared errors.
