(1) The "Delete This Note" button and "Delete All Notes" buttons are adjacent and there is no "Are you sure you want to do this?" confirmation screen. If you are off slightly you delete all your notes at once. Hope your iCloud backup is working.
(2) No "undo" button. Itd be pretty great if you could just hit undo when you do misclick and delete all your notes, but you cant.
I love the simplicity of the interface but for something I rely on so heavily (writing things I need to do, things I owe to people, ideas I have, etc.) I just cant keep using this app. I am a pretty careful person but Ive had my finger slip and lose everything too many times, and the iCloud safety net just isnt enough.
