The idea is pretty simple, Here... In the scoreboard another section should be added preferably at the #1 spot saying "serverid: murder123" or just "murder123" etc. The whole point of this is for bug reports. Makes our lives easier as well gives you valuable data for bug reports.
This would be a great idea, if someone forgets to do the command for it and tries to report a bug, the proof becomes invalid and they'll have to retry for the proof. I'm sure with this it will be way more efficient and simple. +1
