That's nice in theory, but it's also yet another example of Apple innovating and getting it right, and people implementing a quick copy without going through nearly as much necessary design thinking as Apple did. The end result is that only Apple's implementation is better than the default one. Of course I'm not blaming you personally for that, I mean, even Microsoft has fallen prey to this phenomenon (and on a vastly larger scale). But it would nice if people were more observant.
