ADDING Individual cells
Office 2016 has ONCE AGAIN changed a 1-step process into a 2-step process.
BEFORE: If I wanted to add 4 individual cells ... I would click "=" and then click on each individual cell I was adding ... and then hit "enter" to get the total.
NOW: I have to hit the EXTRA KEY "+" before each of the 4 cells I select.
This is just another BACKWARD FEATURE of 2016 that was not required in previous versions.

I disagree with this suggestion. You are only looking at half of the picture. Here is the other half: Before, if you clicked on the wrong cell when you were trying to add a cell reference in a formula, you would have to press Backspace a few times to delete the incorrect reference before you can start over. Now, you can simply click on the correct cell without deleting the incorrect reference first, which is faster.
Also, I don't see any reason why "+" should be the default instead of other operations like counting or averaging.
