Of course, the simple solution would be to make this a user-configurable option. I would much prefer a confirmation dialog box, and it doesn't even have to slow things up much hitting Delete-Enter. At least this would avoid deleting items without even realizing it. Used to be able to fix this in the registry, not sure if that still applies (HKEY_CURRENT_USER\Software\EverNote\EverNote\ConfirmationList\SingleNodeDelete)
