Full Screen and calendar please?

What would make this app ABSOLUTELY awesome is being abe to use it in full screen. I think I paid a dollar too much for something that wont occupy my dinky little 13" macbook screen. I cant even resize the window. And I would LOVE being able to change themes or put a skin to the diary. Otherwise, it serves its purpose.

It would also be nice to be able to export the entries into Word or Pages or something, that wont disappear if I delete the app.
