The only icon in the ribbon bar that I use on the daily Diarium view is the "save" icon at the far right, next to the 3 dots. Sometimes, in a hurry, I mistakenly click on the icon next to it -- the "delete" icon. Fortunately, this mis-click generates an alert asking if I really want to delete. This has happened many times. I would be less likely to risk a major unintended "delete" event, if the "delete" icon was moved further to the left on the ribbon bar, instead of right next to the "save" icon.
