Hi. In the Universal GUI when you say in the SF to put something in the next tab it creates a new section. To have the same experience as putting something in the the next tab.. it would be nice have a section collapsable, so by default it doesn't clutter the screen and you can just fold it open when you want to see these details.
And perhaps it can come with an extra setting to have only one section open at the time or multiple.. just like with pre-filters where you can have only one or more.
Similar to this idea, I'll leave your idea open for the time being; I'll discuss internally if these ideas could be merged 
As this idea didnt have any mockup ive copied them out of my topic
Example how this would look (with some icon added that a section can be expanded):
Collapsed:
Click on “Product” leads to the section to be extended;
This is planned to be resolved with the Roadmap 2025 H1 efforts.
