Extend the concept of content contols from Word to other Office applications, especially Excel and PowerPoint.
I am a member of an open source software development project (https://dotnetfoundation.org/chemistry-add-in-for-word) and we use content controls in Word to display chemical structures. It would be extremely useful for the scientific user community to be able to have the same functionality in the other Office applications. Any chance that content controls might find their way into at least PowerPoint and Excel?
