The names of commands, navigation structure, layout and so forth were refined through many iterations of observation, depth interviews, terminology/categorization studies and usability evaluation (ranging from Expert Reviews to full lab-based Usability Testing with large numbers of participants).
This extensive UX work notwithstanding, many banks want S1's Personal Banking system to be branded according to their own internal standards. For this reason, the ability to customize was built into the technical architecture of most S1 products, including Personal Banking.
One of the first banks to apply a radically different appearance to S1's Personal Banking system was Regions Bank. Their re-design was so good that it was adopted as an example in the official S1 Design Pattern for Navigation. An early version of this customization is shown in the screen shots below:

Regions Bank has gone through a total corporate re-branding and they have refreshed their version of S1 Personal Banking accordingly. To get an idea of the current state of Regions Personal Banking, click here.
