Yeah, I have to agree. The blog post seems convincing when you look at the images, but now that I've actually been playing with it, I can always drag the corner to resize. In fact, the corner provides much more draggable area than the window edges do. There's no problem.

So I agree it's strange that the drag zone extends so far beyond, but that's not really something to complain about...? Everywhere inside the corner where it feels reasonable to resize, it resizes. The article is expecting an absurd level of a drag zone on the inside.

Again, the large drag zone outside the corner is kinda weird. But honestly that's more just an understandable artifact of the corner drag zone being a square. If it were me, I probably wouldn't bother to round off one corner of the drag zone either.

There's a lot of stuff to criticize about Tahoe, but this would be about last on my list...
