Another thing is that classic should be a little more fluent. It shouldn't have to show you it's loading status. It shouldn't need to be visible when it loads, unless the user really wants to see it load, it should be silently loading. It should also be able to support extensions and libraries better so that more applications work with it. Now here is a feature that is very needed.

Many users have Apps they love, but haven't updated in a while. Now when they switch to OS X, many of them won't work. This utility should then automatically load and tell them what the latest version is and how to get it.
