Noticed some cool stuff today when I set the draft order for the fantasy football league that I commish. (Hey, I just used "commish" as a verb. Neat!) Anyway, the first new thing Yahoo did was ask me if I wanted to set any keeper players. I can't recall ever being asked that by Yahoo before, so it looks like the site has just gone a long way toward becoming keeper-league friendly. (A note before I continue: My football league is a Yahoo Plus league. I'm not sure if all of these features are available in their free leagues.)
In addition, Yahoo gave me the option to have a snaking draft (the usual 1-14, 14-1) or a non-snaking draft (1-14, 1-14), which is again another bone thrown to keeper leagues, some of which draft that way. My football league is not a keeper league, but I played around with it for a minute and everything looked intuitive and easy to use. I assume these features will all be available for Yahoo fantasy baseball leagues next season.
