The tabs. First of all, they're Safari-style tabs and Safari has awful tabs. And then there's a preference called "open folders in new tabs instead of windows". Open up a Finder window, open Terminal and run `open /path/to/directory`. What happens? Directory opens in a new Finder window.

There's no way to have Finder remember what size a window should be. There's a bunch of tricks that people post online of how you can have Finder remember a window size but they don't work. It might register it on a folder-level but then you run `open /path/to/directory` and it opens up a postage stamp sized window (even though it should open a tab).

And where the hell is cut and paste?
