Thanks for the feedback! - preview screenshot added just now.
It's funny how easy it is to miss those simple things despite having looked at it for so long.
I still don't quite get it. I can scroll my mouse on Google Calendar looking at the Saturday and Sunday columns. 12 clicks of my scroll wheel and I've seen my year of weekends. In your screenshot, I scroll left-to-right and Sat/Sun are combined, but I am not understanding the benefit of that.
The screenshot is just a small snippet, zoomed in for clarity (and to avoid sharing PII from my actual calendar) but I actually see about 5 months ahead at a time with zero clicks/scrolling on my standard browser.
Also I find the horizontal timeline view helps to spot clusters of too-much-going-on more intuitively than the typical wrapped view of a calendar block.
