Overall this is pretty good software. Could use a few refinements: 1. It would be nice to have per-folder encryption and chunking, just like you have per-folder versioning. For instance, I have photos that I want to be publically available, but I also use S3 to backup sensitive data that I want encrypted. What a pain that I have to keep changing the app-level option every time I change the type of data I am backing up. This should be a major priority to release ASAP. It is a serious handicap to the flexibility of this software. 2. Need some shortcut keys. For example, F5 is pretty typical for a refresh, whether in the Windows OS or in individual apps like web browsers. It would be great to have an F5 refresh of the view. 3. Along the same lines, need some whitespace context menus. If I right-click with nothing selected, I should at least get a context menu with a "Refresh" option. In the normal folder view you do have the refresh buttons. But in the Compare Folders view on a high-res screen it is really annoying that the only way I can refresh the view is by moving all the way to the right to the "Compare" button. A context menu and an F5 key would really help.
