Shared File/Folder changes notifications.
Dunno if this one has been posted yet, I see some stuff that's similar, but not really exactly the feature I'm looking for.
In particular, my mom has shared with me details about a planned trip out of the country via one-drive, and I'd like to get a notification if she makes any changes to her plans, so I can keep tabs on what she's up to over there.
And now that I'm thinking about it more, and reading the post below this comment box, it sounds very similar to that... >_<
I'd like a digest of changes, and I'd like to be able to configure it to send them to me on a monthly/weekly/daily basis as she gets closer to the date of departure. There's probably more to this user story that would be really cool, but that's the functionality I'd be looking for... XD
