I just uploaded the newest version : 0.8.0 with automatic folder watching/background monitoring.
I'm excited for this release because it allows the user to set and forget iTunesDSM to check a folder for new music and automatically add it to iTunes! Something my family surely needs with 4 of us adding music all the time, it's hard to keep our iTunes in sync.
Windows users - there is a new installer for you.
Mac users - it's the same as before - run the jar file.
I've uploaded some new screenshots and updated the release notes.
