Statistics: Count selection
The viewport statistics should show the count of the current selection by default. If you need Total statistics, a single Ctrl-A will do it.
I agree that we need both options and I would love to see the faces selected count.
I support this idea but with a simple exception. "A single Ctrl-A will do it?" How about a scene with thousands of objects and millions of polygons. Sorry, but it's not as simple as that. I prefer to have both total and selection on by default.
