It is too big and in the centre, holding my tablet horizontally I can barely press the the upper buttons and it also occupies a big part of the screen, it doesn't need to be nor that big (both height- and widthwise), nor in the centre. The tab menu is also no better, when the grid mode is enabled, the icons are too big and now less fit on the screen and the "+ New tab" button is in the centre which is again an uncomfortable position. Please, either re-do your layout for tablets or, even better, keep the old menu.
