Changing the look of the buddypress bar

I've seen a few themes that have a different color and layout to the top buddypress navigation bar.

I have customized this before but it became a pain to manage after doing a few upgrades.

Is there an easier way to customize the look of this gray bar? Or, wouldn't it be great to have that as part of, let's say (hint hint) the bp-corporate theme? :slight_smile:
