Google Ads is testing (or rolling out) a new overview design for the advertiser console. It lets you pick which metrics you want to show in that view, and you can then scroll through them horizontally if they don't fit on the screen.
Anthony Higman spotted this and posted on X, "Google Ads New Overview Slide Metrics Dropdown/Carousel. This is actually SUPER cool! Let's select ALL the metrics and then click through on the right to see other things in the overview slide!"
Here are some of his screenshots:
I don't seem to have access to this feature, at least not at the time I wrote this, so maybe this is just a test or maybe it is still rolling out?
Forum discussion at X.
Update: Google confirmed this as a test:
Hi Anthony, We’re currently running an experiment with a limited number of advertisers to offer more flexibility from the overview page.
