Just a simple little thing, but wouldn't it be kind of nice if you could close a running application by just dragging the icon out of the dock? this would be really nice for programs such as Preview, Text Edit, Quicktime, etc. that you open up just while doing web browsing but they remain running and in the dock. it would be nice just to be able to drag them out of the dock, instead of clicking them and clicking quit. (I know you can use CMD+Q but what if you have already closed the window?) it's not a major thing at all, but I think it would be really nice. it's like so many other things that are nice about OS X. all those little things. any other little things you guys can think of that would be nice if they were added?
