nice update, especially the search bar and the autorotation!
but, the icons don't rotate to all 4 directions, if I turn the n900 to the left, the icons are upside down, would be nice if the icons could support all 4 possible positions

also, if you build a horiz dockbar with 10 icons, then switch to vertical, you can't open the prefs anymore, cause the prefs-icon is outside the screen maybe autoresize the dockbar to max width/height?
