The Shared Folder
I've been a big fan of Foldershare for a while now, and this feature absolutely kicks ass. I have used foldershare to keep documents and favorites in synch no matter where I am, but now I can synch up all my indexes to not only find where it is on my computer but on which computer it resides! That is so cool! Next step? If I do not have it in a shared folder, allow me to share the document it found automatically, based on my permissions.
