That was my initial thought as well, but as I noted I chose to go with convention re: Chrome Inspector. I think it's debatable whether or not it uses a sane default (the UI will hitch up on really deep breakpoints) but I didn't want to create any confusion. As long as this option is very visible I think it'll be fine at a lower number - say, 50, which ought to cover 99% of use cases (as you're generally not going that far down the stack). Good with 50?
