Feature request: ability to filter `(anonymous)` frames

[miniBill]

When loading profiles for node applications there can be a lot of (anonymous) frames that are not super helpful.

It would be nice to have an option to hide them all.

There is actually a way to filter functions, but just tried your use case specifically locally and it looks like it's not working.

Normally you can right click a function, and select "Merge function" on the context menu. And this should collapse that function in the whole call tree.

This is not really working for your use case because even though they share the same (anonymous) name they are actually different functions. So the Firefox Profiler never collapses all of them due to that.

I'm not so sure what the best way to have this ability would be. Maybe we can put them in a new category JavaScript::Anonymous and add a new transform called "Merge functions in <category>"?

Yeah, the Merge function feature is fantastic but doesn't help here.

This might be a more generic "only show frames that match/do not match this filter"

If there search field is non-empty, we could provide transforms like Merge functions which match "<current search filter>" and the inverse. Then you could search for (anonymous) and then apply that filter.
