[Feature]: Button to expand/collapse folders in the file surface #4227

Before submitting

• I searched existing issues and did not find a duplicate.
• I am describing a concrete problem or use case, not just a vague idea.

Area

Not sure

Problem or use case

I have a folder with many sub-folders with many files. Opening the file surface expands them all. There is no button to shut them in one fell swoop. It's a pain to find what I need in there because of it.

Proposed solution

A button to collapse all folders in the file view (and maybe naturally one to expand all?)

Why this matters

Me

Smallest useful scope

Not expanding all folders by default (or even after I've manually collapsed them all and just reopen the surface)

Alternatives considered

I manually close them all.

Risks or tradeoffs
