Reposition icon group in the task bar to support superwise screens

It would be great to allow the taskbar icons to justify not only to the left but also to the right or center of the taskbar. This is particularly valuable for superwide screens (say the 49'' 32x9 monitors) where the left-justified taslkbar icons require a head rotation before inspection. If icons could be center-justified, that would improve usability for such monitors.

Alternatively, adding a variable-size separator feature could achieve the same trick.

Is either of these possible?
