Can't remember seeing it being discussed (but my memory is not perfect, I don't read all threads and I've only been here half a year). Personally I agree with min34, that seems to be the easy solution. However, if you still want to propose it, the easiest (and "official") way to make the suggestion is by going to UserVoice.
) you can type up the suggestion (think "elevator pitch": keep it short and clear; feel free to give a little thought to the phrasing, because once you've posted it, you can't change it any more). Then post a link to your suggestion here, in this thread, so people who agree with you can easily find your suggestion.
Of course, if (almost) nobody can even be bothered to post an "oh yeah, great idea!" post here, your chances of getting a lot of votes on UV are slim... (Then again, this thread's only been here for a handful of hours; supportive comments might still be on their way!)
