Stories linking to other stories without new windows

When clicking on internal links to stories, it opens another tab (or window) for me. I don't really need this window... it would be great if it just "reveal"ed it in the current window. This would make it more usable to link to other stories.

This could actually be pretty easy to implement... when recognizing URL, if it looks like /https?:\/\/www\.pivotaltracker\.com\/story\/show\/\d+/ replace it with the javascript behind the "reveal" button.
