Viewing Workbooks in Office 365 Excel (2013 and later)

In Excel 2010 and earlier, you could resize the view of the open workbook to take up only part of the Excel window's workbook space. This allowed you to view more than one workbook at a time AND to also save the size that the workbook would open at when transferring it and viewing it on other computers with different monitor or screen sizes. It appears that Microsoft has removed that capability in later versions of Office. I have not been able to figure out any way to do this. You cannot even view 2 workbooks side by side or top and bottom any more. I tried the View, Arrange settings, but they do not do anything. If anyone has any ideas on whether there is a way to do these things any more or if I am just stuck with the one workbook at a time only setup, ideas would be appreciated.

Thanks.
