I have been reading a great article by Joel Sposke about usability while negotiating the release of the brown hostages at work...  (think about it)

A great point made by the author is that you should not provide features that very few users will ever find valuable.  Particularly, you should not provide customization that is beyond color schemes and window preferences.  Example, don't let the user drag the menu around.  If it is a File menu, put it at the top and leave it there!  “but users want the ability to put the address bar above it if they want too, whah whah whah...”  NO, they don't!  In fact, it happens almost daily that I accidentally move a menu bar when I try to click it. 

Then it happened today.  VS.net allows you to drag your file menu off the screen, apparently.  I say apparently because I had no intention of doing so.  Somehow, my file menu is GONE!

I know how to reset all preferences to default because this sort of garbage has occured before.  I did that but it did not restore the menu.  I now have “edit, view, tools, window and help”  great! 

The point is, if a feature is cool and nifty but not really part of your applications primary utlility, be very careful about what you add...  It might make a user's day hell.
