Quick Face Alignment

Currently if you press Alt+MMB and drag your view will be aligned Left, Right, Front, Back, Top, or Bottom depending on what direction you drag and how close you are to a given alignment.

I propose that Alt+Shift+MMB drag aligns the view to the selections Left, Right, Front, Back, Top, or Bottom based on averaged face normals. So if you have one face selected you could align to it's Top easily! Which I would do more regularly if it wasn't awkward to do as it currently is.

The thumbnail shows the menu. Sorry I haven't attached it in the post, I'm short on time. :P
