----------

We could optionally filter out anything with a "Prototype" suffix and count of 1, but if there are iframes you get counts of 2 or 3 or more generally numberOfIframes + 1.

I guess we could have an option to just filter out all object prototypes.

We also have vague plans about enriching the filter language, so we could make a filter string of "-(Prototype AND count < 1)" do the Right Thing(tm) but I think that is a little too much manual work than this request wants and is a bit more niche.

----------------------

Aside: I would definitely want to keep this as an *option* not the default and unchangeable behavior because if these prototypes weren't there then I personally would be confused like "where are all these things that I can verify exist in the console???"

that's exactly what I meant, a few more examples

HTMLLinkElementPrototype
TextEncoderPrototype
HistoryPrototype
HTMLDivElementPrototype
DOMImplementationPrototype
DOMSettableTokenListPrototype
HTMLUListElementPrototype
CSSStyleDeclarationPrototype
HTMLFormElementPrototype
Uint16ArrayPrototype

being able to sort the columns would also help
