Can anyone tell me what is the difference between the yellow arrow button and the blue arrow button? I guess the yellow one only synchronizes the currently selected profile whereas the blue one synchronizes all profiles... But if true, why the yellow button is a single direction arrow? Does it mean it only synchronize from the remote calendar and not to it? I'm confused by this icon as it provides two different informations: the "1" seems to indicate that it will only synchronize one profile, the single arrow seems to indicate that it will only synchronize in one direction. Halp. :[ By the way, great app!
