A traditional feature of files, which is visible in context menu in Explorer or inside an appropriate program, is "Properties". However, for OneNote files it is not implemented. It may be useful for archiving purposes or if an author decides to send this file to someone else. I suppose, to show some statistics would be a good idea: the name of author, the total number of notes and sections and, maybe, the date and time of first and last note (= file creation and last edit)
Also to see the properties of a single note in OneNote (probably with context menu) will be another nice feature. This information could also include the date of note creation and its last edit (of course, if these stamps are storing in the file), some statistics such a word count and characters count or note size, and note type (what does it contain: text, handwriting, graphics, multimedia etc). The separated objects such pictures could have their specific property sheets (dimension, zoom, original address or location, and so on).
