I don't understand why that entry doesn't show up for you. It shows up for me, and is also in the list when I search for "last playlist". Although there are so many entries with hits for that word combination as to makes the search useless. Interestingly, it's even worse when I search for "go back to last playlist" as opposed to better, as I would have expected. It seems the FAQ search doesn't do a word-proximity-relevance search. Too bad.
