It is surprisingly hard to figure out how to view your OneNote 2010 notes by date. A common scenario is that I want to view the notes I took yesterday. In both Google Docs and Evernote, this is the default view (all notes sorted descending by date).
In OneNote 2010, here's how you do it:
Share Menu->Recent Edits->Since Yesterday
This will find all notes, sorted by date, since yesterday.
Seems like this should be in the "View" or "Review" menu, as opposed to the "Share" menu.
