So I just updated to epel-testing, then noticed that i lost round edges (the .button, .action {} css section needs border-radius added). So I grabbed the latest releast of style.css and put it on my box so I could do a quick patch file on the issue, and wow... umm ya. So I went and looked at the changes and I see that james had to do quite a bit (20 adds, 25 deletions) for the new tabbed interface.
The only problem with that is that it affected more than jsut the tabbed interfaces.
The main issue is that to accomidate the smaller width on the tabbed interface the content div was adjusted to be a static width of 850px. Since the tables and the forms share the same parent div, I can see where you were going, my concern is just the overall effect. most of the tables are fine with this change, but not all of them.
I provide screen cap
