Great collaboration app!
This app magically makes SharePoint something digestible. The one item which Ive found needs refining is the in-app editor and the preservation of notes / comments from in-app editor to downloadable working version. Ive had to re-enter any comments Ive made on note sticky tabs as text boxes (for them to be readable in the downloaded and printed document version).
