You have to hit the "Edit" button before you can edit anything. I'm falling into that trap everytime, too.

Another quirk in the user interface is that it doesn't save automatically, and it lets you quit without warning. How many times did I enter a complicated password with the satisfied feeling of having it backed up once and for all, just to find it missing when I needed it later.

Having said that, it is one of the essential apps for me, too, so thanks for the good work. It is much appreciated!
