It would be nice if you had a "username" per-se and all your secrets would be prepended with that. Even if it's just a 8 character random string that is in Preferences, that would allow for more entropy. Another thing that would be useful (which I kinda brought up in another post), would be an option whether you want to create a *new* folder or add an already-synced folder. If we had that option, then if you were making a new one, it could check for collisions when it generated a secret and tell the user that it already exists or just generate a new one.
