Save us of clicking their profile, going to their league and clicking on Live button :D
That's still only best case and assumes the two of you are at the same level. For example I am in the "Pro" level and my wife is in the "Rookie" level I can't use that workflow because I'll end up watching the "Pro" race.
I think if you lower the race ID number of the Pro race by 1 the viewer should load the Rookie race. Still, upgrading the friend list with that button would really be the most convenient and sleek solution and this game is all about live racing, isn't it. Once we're at it it shouldn't hurt if the tier tabs of the league area would show a button leading right to that tiers race.
