Oh, yes, I get the logic, from a consistency standpoint. My only concern is that a) it's unnecessary, because `widen' is available, and b) some day we might think of a better special meaning for C-u 0 (and in the meantime it could error instead of narrowing to the current level-1 subtree). But I don't feel strongly about it either way. Perhaps consistency is desirable here, although I tend to think that consistency is overrated in UI/UX in general -- the famous example of "`transpose-chars' at the end of a line" comes to mind. Hmm, but on the other hand, your proposed consistency *would* be good if anyone's ever calling `org-narrow-to-subtree' from Lisp with an algorithmically calculated STEPS argument. I can't imagine what kind of circumstance that would be, but if it's a general principle of Org Mode to consider "level 0" to be the entire buffer, then we should probably go with your proposed behavior. So I guess I'm tentatively +1... Does anyone else have any thoughts on this? Best regards, -Karl
