Is your feature request related to a problem?
If a trace lasts a long time (over an hour) and it contains spans which last only seconds or tens of seconds, those spans will be very poorly visible.
Describe the solution you'd like
Allow us to click and drag the summary of the trace in order to display spans only from a certain interval of time like in the logs explorer or like what's possible in Jaeger.
Describe alternatives you've considered
I think at some point it was possible to center on a given span, so that only it and its child spans would be displayed, but then the feature seems to have been removed or at least I can't find it anymore.
