[Feature request] Confirm before delete?

[Darthagnon]

I was testing the latest release 0.5.7 and noticed it's very easy to accidentally click the red X and delete a field. Would it please be possible to add a confirmation before deleting (Are you sure you want to delete this detail? Yes/Cancel/X/Do not show again)?

Or even better, an Edit mode like on iOS? Click on Edit, and fields are editable/deletable/addable, with Cancel replacing Edit. When not in Edit mode, fields are all copiable, but cannot be edited, deleted or added (new contact can always be added).
