I don't know if the wish list is the best way to get AC's attention for suggested enhancements, but it does allow users to become aware that others want the same enhancement they do. If you feel strongly about the enhancement, then sending in a Recommended Imporvement from the Help menu in AC is probably the way to go. If enough people request the same thing, it probably only then gets into the "future enhancement queue."
For Updox, you can do the same thing from within Updox by selecting "Contact Us" I believe.
