Not yet (I’m a solo dev so it is quite hard to do multiple builds). Patches welcome! :)

Somebody might find that behavior a bit making nervous if you don’t see progress, that it is running or that it was synced a few mins ago…

That’s why for that “daemonic” behavior programs hide themself in system tray :)

I think because of that they do not implement “selective sync” feature, i.e. when you need to sync only a slice of remote directory.
