We would like a "private" folder that items could not be shared from. If you want to share something in the "private" folder it would have to be deliberately moved to another folder. We want to make sure anything shared for onedrive is deliberate
Users will be able to share a link to Office documents that blocks recipients from downloading copies but still allows them to view the document in Office Online.
Users can create links that block download by using the common Sharing experience that exists across Office 365. By going into Link Settings they’ll be able to toggle the “block download” option for view-only links.
We’ve completed rollout for “anyone” and “people in my organization” links, and are working on enabling it for the remaining link types.Ross commented
How about a feature to prevent sharing anything a "private" folder, you would have to move items you want to share to different folder. This would prevent things from accidentally being shared
