MTFLY  Outstanding app. This is the best viewer I've found for the mac so far. When you don't need all the overhead of file management and use a separate editor, this app is perfect. Fast as well. Surprised it's free!

Beyond the edit capability to another program mentioned below I have two more suggestions:

1. some ability to sort the files other than by name, date modified, size, type and finder label.

2. Hot keys or some other mechanism to move files to another folder quickly.

Great job, Thanks Marc
