Malcolm, don't give up. OF-the-application is actually quite mature, I've never lost data in six months of using it (I have all the backup options turned on, and I've never needed them), and it takes time to get familiar with it.

A manual will help. So will some patience and a willingness to play with the application.

You may feel more comfortable with unimportant data; I'm assuming you already have another process you're using. Keep using it while you try out OF, rather than using it as your only action repository.
