Safari 4 Beta

so i just tried safari 4 beta, and i’m quite impressed, but it’s strange that it’s almost exactly like chrome. It’s like Chrome’s not only based on Webkit, but Webkit is based on chrome. Sorta like Vista = OS X, Gadgets/Widgets, Search/Spotlight stuff.
I’m somewhat annoyed about not being to close tabs with middle click, and how, unlike Firefox+TabKit, it only has that small possible tab space. Especially since i have a disfunctional mental garbage-collection system, so i easily have >20 tabs at a time.
