I really think they got the right idea by making it look more "mac" window/finder like....

But they totally missed the mark by putting so much white space and padding around everything.

The minimal size I can shrink the window to is still >=33% of my 20" monitor, even with "Compact Sidebar" and smaller font.

They really should have studied the Mac OS user interface a bit more before releasing this. It seems like they fell into the whole lots of white-space and big font web-design trends...
