Extend window when activating side bar (like a drawer)

When you view/invoke the side bar in Sublime Text 2, the width of the window stays constant—the side bar appears on the left, code in the middle and the mini-map on the right. This usually “squishes” the code view…

It would be nice if there was a way to keep the code and mini-map locked to a specific width and force the window to grow wider when you invoke the side bar. Displaying it as a "drawer" is not really necessary, but making the window expand is mainly what I am suggesting.
