right now, in compact mode, the url bar starts in the middle for a new window and it moves to the left incrementally after new tabs populate on the right side.
making the url bar stay at the same place in compacy mode will prevent the UI element jumping too much which would feel more stable and less distractive.
here is a markup of the proposed effect.
the url bar might feel too long when compared to a single tab in this case so maybe can even reduce the length a little bit to make it look better. (i also place the + right beside the tab, placing the + on the far right is just too much work to reach to)
