Zimbra won't let me set up a folder under (e.g.) Tasks with the same name as a folder in (e.g.) Briefcase. I guess that may be because, under the skin, these are something like IMAP folders under a common namespace. I tend to group my documents under the same headings as I group my emails, tasks, etc.
Is there any possibility that this will be turned from a limitation into a feature, by allowing the sharing of folders across the various applications, with the ultimate end of adding an interface that allows you to view in one place all the items of the various applications that relate to a particular folder?
