Thanks Michael and Mr Numbers, believe it or not, I never noticed that.....

My process tends to be to open the page by default on my browser on the SE23 section, see what's new and typically not look at the other two sections.

I still think a view all posts as opposed to new posts which merges all sections would be useful, but I'm probably just trying to save my blushes for not seeing what was right in front of me.....
