The styling of the last selected panel bar item is inconsistent between the themes. For example, with Office2010Blue, selecting a panel bar item sets the background color (via t-state-selected) to orange. However, with other themes, such as Metro, selecting a panel bar item causes no change in the background color. I imagine this is intentional, but it does make it more difficult to switch between themes and have consistent behavior.
I am using the panel bar as a vertical menu in the left hand side of a splitter window where the details for the selected panel bar item is displayed in the right hand side of the splitter. My preference is to have some indication of what was last selected in the panel bar list, so the user can associate the detail window contents to the selected panel bar item. I know I can style this on my own, but prefer to stick with the CSS provided.
I also noticed that the styling is different between the ASP.NET AJAX panel bar and the MVC panel bar (with ASP.NET AJAX Metro theme the background color of the selected item is different).
