I tend to agree with you, Tim.
If I only wish to respond to a small part of someone's comment, I usually just select that part of the original comment and a 'box' will appear on my screen with "Quote selection" in it. If I click on that, it will appear in the comment box. That's what I did to get Tim's comment above to appear.
I'm not sure if that's as easy to do on a smartphone or tablet, as I always use my laptop for GA.
Yea, Tim. Stay safe, buddy.
(See what I did there? After responding to Tim above, I went back and selected dug's comment, so I could then quote that in the same reply.)
And there I was thinking I was the grumpy old guy in here. I'd never have considered you grumpy.
