Subject: Re: [PATCH v7 5/6] perf report: support time percent and multiple
 time ranges

One more thing to consider:

When you use:

   perf report --time 10%/1

it will do what is asked but there is no indication of what percentage
ranges are in place, it would be nice to have this in the first line in
the TUI, right after this:

Samples: 128  of event 'cycles:ppp', Event count (approx.): 21386169 (10%/1)
