Holes in IE7’s Tabbed Browsing

One of the things I love about tabbed browsing in Firefox is how consistent the middle-click-to-open-a-tab behaviour is.

For example, if I middle-click on the Home button, my home page opens
in a new tab.  If I middle-click on a bookmark in the Bookmarks
menu, same.  Middle-click on a quick links bar icon, same.

IE7 missed out on this.
