Very nice!

Easy, fast and smooth. Ive tried similar apps with other NAS systems and this is the best.
I love the new photo browser.

One thing that would make this perfect is the ability to download a folder.
Other thing is, when playing media files, an option for it to automatically play the next file after the current file has been played. I sometimes use dsfile as a music player for albums I didnt get the chance to sync through itunes.
