Send attachments from Dropbox one drive etc as links instead of as files
When composing an email and attaching files from storage services like Dropbox or onedrive, allow the user to select if they want to send this file as an attachment embed in the email or as link so that the recipient may download the file. This is particularly useful when the file stored on Dropbox is too big to be an email attachment
And select more than one file to and when are files, attach more than one instead of return every time in the browser.
And from iCloud drive

Or just integrate into the Dropbox share link?
