Expanding a Collection to full-screen

I miss the option to quickly expand a Collection to full-screen.
The side menu, as well as the library section, are often not needed, often you want to see more of the content in the Collection.

Request:

A left-click on the title of the shown Collection should expand it to full-screen.

A dedicated button would also be an acceptable alternative, but I believe there is no need for that. It's also more comfortable to make a quick click on the big title, compared to a tiny button somewhere, or a right-click option.

If you believe that a single left-click should be reserved for other things that may come later, then implement it as a double-click.

(The video shows nothing special, only my desparate but hopeless tries to get the Collection to full-screen by clicking again and again on its title.)
