Suggested feature: Password required for diary removal

Hello.

First off, thanks for creating Lifeograph. I'm a new user and very much enjoying it.

One thing I wish it had though, is the authentication requirement when removing a diary. I find it vulnerable when you need to enter a pass word to read/edit diary when somebody can just delete it totally. I know there's an undo function but once you close the window there's no way to retrieve it, yes?

Apart from that, it's a totally awesome app. Thanks for bringing to life!

Cheers,
