An option to have the default level sharing permission 'view only'. At the moment all sharing links are edit by default but it's not obvious to the user from the 'get link' or 'share' dialogue box that they have to click on the link to change the settings. So whilst we need the option for external users to have edit access to content that's shared with them, this would not be our default unless it was clear at the point the end user is getting the link that they can change to view only. Please make this more obvious.
