It would be useful to be able to toggle/flag into a process-level mode to group by pid and display more process-level information like the full command line.

• For the "Utilization by process name" window, we could group by pid rather than process name so that it's easier to find specific heavy network resource consumers.
• For the "Utilization by connection" window, including the pid + cmdline would be helpful in distinguishing processes without extra work to map the port to a pid.

I can give this a shot. I've been looking for a small PR to get some exposure to Rust anyways.
