I visit our SketchUp forum ump-teen times a day and use the New and Unread buttons exclusively.
When I’ve read the posts I’m interested in, I dismiss the rest.
The red ‘last time visited’ line is a mystery. I haven’t noticed it move up or down, it just sits there.
What that means, I haven’t a clue.
Why add unintelligible clutter when the New and Unread notifications clearly tell the tale?
