I found that getting rid of the text-align parameter will actually make the text left align. Problem is i couldnt figure out which one to change. The naveboxes look really bad with the group box off to the side but all the contents still centered.
Thing is, for a lot of navboxes text-align:left makes it look even worse. (And even *more worse* if you use scripts to remove the right rail, and the article takes the whole width of the main canvas than the itty-bitty space it usually has.)
I don't really know how to deal with this right now. Group headers to the left is the way to go - the way they were to the center previously is a very inefficient use of space. But yes, there are some issues with figuring out how to align the text so it would look the prettiest.
