... but I really wish interface designers would realize that taking choice away is a bad thing . If your users have become accustomed to doing something one way and you want to encourage them to do it another way, fine. Change the default settings or whatever. But you should almost always leave them the option of using the methods they're accustomed to. The one exception I can think of to this is when leaving the old interface in place will truly, fundamentally break the application--and really, how often does that actually happen?
