Ok, the MC9 smartlist editing interface has GOT to get better...
I have a smartlist that goes:
[Genre]=[Arabic],[Bollywood],[Brazilian],[Folk/Rock],[Indian],[Latin],[Lounge],[Merengue],[New Age],[Pop, Japanese],[Reggae],[Salsa],[Tango],[Tribal],[World] [Intensity]=<=3 [BPM]=<=70 ~sort=[Random]
And I wanted to edit it to:
([Genre]=[Arabic],[Bollywood],[Brazilian],[Folk/Rock],[Indian],[Latin],[Lounge],[Merengue],[New Age],[Pop, Japanese],[Reggae],[Salsa],[Tango],[Tribal],[World] or [Playlist]=[World Soundtracks]) [Intensity]=<=3 [BPM]=<=70 ~sort=[Random]
Well, you can't imagine what a trauma this was - the "Insert Modifier" or "Insert Rule" only inserts at the end of the playlist, and typing directly [Playlist]=[World Soundtracks] doesn't work - you have to type '"playlistid==409169973", apparently.
It was completely unpredictable as to whether I was editing at the token level (underlined phrases) or at the character level.
And of course, all this within a one line box that only showed me the first 30 or 40 chars of the smartlist definition, so I was constantly having to right-click to select "Edit by typing" after scrolling back and forth.
iTunes has shown us the way forward in this one area, it would make life sooooo much easier.
