Implement the Check-in/out function for the modern UI as well.
I am aware of the Check-in/out function is available from the OneDrive screen in the classic experience, but it cannot be displayed in the modern UI. For increasing Usability, I hope the feature to be able to use the Check-in/out function for the modern UI as well. In addition, it would be great if the feature will add a function that disenables editing in the modern OneDrive screen due to prevent the unexpected document duplication occurs when collaborating on Excel Client as well.
Here is the reference for Office365 features in March 2017.
Title: "Excel collaborative editing, etc."
Thank you for your continued support.
