While we're coughing up a wishlist, here's something I bet has been mentioned in the past, but is enough of a biggie that it bears repeating, IMHO:

I'd love the ability to spectate games.

We're about to kick off the playoffs in my league (I finished dead last, fwiw, but I'd drafted for next year when we use the 2006 data -- Francisco Liriano, me boys, and Joe Mauer, and... :). A bunch of us would love to kibitz the games and yell at the umps and stuff, but joining for chat doesn't let you see even the play-by-play. Sigh.

It'd obviously be a v10 thing, not a v9 patch capability, but MAN it would be fun!
