"In VS 2010, we made a design decision to move the “X” from the right side of the Tab Well to within each tab. The majority of feedback around this change was positive, but, as with most UI changes, there has been a vocal group that preferred the older placement. When asked what they liked about the old placement, 99% of the time the response was, “I liked the ability to quickly close tabs by repeatedly clicking on the ‘X’ without moving my mouse."
