Gotcha. I can just manually added this change over then. Thanks!

The only nuance to this however is that any secondary buttons must come first given the new style. You're aware of that change, yes?

Hmm, I have to say I prefer the current behavior, with the primary button being rightmost and first in the tab order. It seems that different OSes have different conventions regarding this.

Yup, going to leave them as is with floats. This way, if styles are turned off or if you wish to change them as a developer, the markup does not need to change. The primary button should come first in the markup and the CSS should change the order if need be.
