Slowly, solidify is improving. Bidirectional synchronisation should work now, although this does not make any sense yet, since the file system is still read-only. However, all the foundations are laid now and things should improve from now on. The user interface is still rough, and a non-writeable file system is largely useless for now. Unfortunately, my time is pretty limited currently – my dissertation comes first.
Nevertheless, if you want to take a look at it, get it here.
