Extend the "mouse targets" to infinity - a.k.a. "Fitt's Law"

[logixoul]

When I want to select another tab, I just throw my mouse pointer to the left border of the screen and click (without aiming horizontally - only vertically). But in Zen, this doesn't work - this browser requires me to move my pointer to the right several pixels before it'll accept the click.

So, my feature request is:
If Zen is maximized and I click on the leftmost pixel of the screen (right next to a tab, i.e. x-coordinate = zero), this should switch to that tab.

Similarly, clicking at pixel (0, 0) (top-leftmost pixel of the screen) ought to open the "ellipsis" menu. Etc.

Btw, it'd be even easier to click on a tab if the tabbar was horizontal, because then more of its border space touches the screen edge. But I know the official decision is to have only vertical tabs, and I guess I can live with that :)
