It doesn't work well together with call chains.
It only considers the hits on the leaf function, but doesn't hide
the individual call chains leading to that function which are below
the limit.
So if you have a lot of different cold callers you still end up
with far too much output.
Also would be nice to be able to set it dynamically from the UI.
