Yes, totally. It's up to you to add a gutter. I really like this
rule a lot, but I'm dying to argue about it. Is it very wrong?
I'm dying to know why you particularly like it so much!
If the app is supposed to be scrollable, why not have a greyed-out
scroll bar if there is too little height to scroll? That avoids
worries about adding your own gutter: how wide? the same on every OS?
Of course, I have come to expect the automatically appearing and
disappearing scroll bar. Here's a question for Edward Tufte: is a
greyed-out scrollbar more or less "computer administrative junk"?
