UPDATE- Thank you for all the great feedback on KFM. We are checking every day or so for new questions from all of you.
I wanted to take a few minutes to address Favorites as it has come up several times in the comments.
We have no plans at this time to add Favorites to Known Folder Move (KFM). KFM is a tool to help enable users to easily migrate their files to the cloud so that they can have secure access to their content from any device securely.
There are several methods available to synchronization favorites including Microsoft U-EV (built into Windows 10 Enterprise) and other ways via scripts to back up the data store folder that I might recommend as part of your device restore toolkit.
Finally, we have updated our KFM documentation. You can find the updated document here and here
