Why doesn't Task Coach ask for confirmation before deleting things?

Many books on human computer interaction (e.g. "About face" by Cooper et al) advice against confirmation dialogs. Software should make the common case (you hit delete to actually delete something) as simple as possible and at the same time cater for the less common case (you hit delete but didn't intend to delete something). That's exactly what Task Coach does now by means of unlimited undo.

Also, we plan to change Task Coach so that tasks can be shown and edited in panes, like email programs show email messages in an email message pane. Since these panes are not dialogs, it wouldn't make sense to have OK and Cancel buttons on them.
