There is a plugin available for One Note called onestastic https://omeratay.com/onetastic/ which basically adds a bunch of time saving features to OneNote.
One thing that Michael Anderson from Carl Stuart recently brought to my attention was the really cool ability to generate a report that showed all of the notes & objects that he used in a calendar format (all hyperlinked).
Something like this would be a brilliant report if we could replicate it, I think all of the sales managers who use ProspectSoft would be seriously impressed if this was a feature.
