One suggestion, so far. On overdue task documents that are marked red, the red color should disappear once the task is marked completed.
And a typo. In Help:Clone a Document, it says: "If you want source documents subdocuments to be cloned too, check the Clone Subdocuments option. (Note: if you later add new subdocuments to the source document or to the cloned document, these changes will not by synchronized)" That should be "be".
MI4 is great! I really like the new features.
