Ctrl-Click exemplifies their attitude of mind...
1) Adding Ctrl-Click would not mean removing Shift-Click - it could work as now or an option could be provided to open-in-new-window (as IE and Firefox do).
It's also worth noting that Shift-click was always inconsistent for opening a new tab because it used to open a link in a new window as far back as IE4 (and maybe further back than that).
However, even ignoring that - not being able to tab between links (because links can't be focused) constitutes an accessibility problem. It also represents a failure to follow standards - I seem to recall they make a big thing about following standards when it suits them.
I am also less than convinced that placing the navigation bar below the tab bar is logical, nevertheless details like that I can live with. However, both the tab bar and the navigation bar waste space - very annoying. When you consider that not displaying the menu-bar serves only one purpose - increasing the page area - wasting space isn't just annoying, it's inconsistent.
