For those of you wondering what happened to this application, I am sorry to say that it has been discontinued.
I became too busy to continue development of Ivy and so therefore am pronouncing it, as much as I dislike the term, VaporWare.
However, for those looking for the same functionality, please check out Artwork (http://www.macupdate.com/info.php/id/26056/artwork). It's got most of the functionality of Ivy, with no bugs. It's also being developed by a dear friend of mine, so go and show him support on his first public app.
Developer of illis
P.S. Please don't take this as plugging Artwork, I'm merely trying to make up for the fact that I can't develop Ivy anymore.
