"Detect Fragments and Run-On Sentences" feature in Word 2016
Previous versions of Word detected fragments and run-on sentences, but Word 2016 does not. This is especially problematic because these are two of the most common writing errors students make; many students relied on this feature to improve their writing
Please vote to have this feature added to Word 2016.
