Tab Scroller hooks into some of the undocumented bowels of the Home Server Console to allow you to scroll through your tab list (when selected) with your mouse wheel and even removes itself from view moments after being loaded so as to stay out of the way.
Note: This add-in can be installed on machines with less than 7, however on such systems it can cause some visual artifacts (non-functional scrolling buttons, an empty space where this add-in used to be) only so long as the add-in is installed and there are less than 7 tabs.
Usage: After launching the Home Server Console, use the mouse wheel to scroll up or down through the list.
If nothing happens, click on one of the tabs (so as to give the container holding them focus) and try scrolling again.
