Death messages would make tp trapping a lot easier to report, as otherwise most people aren't recording every transaction they do.
Support, but tbh not for that reason cause I think recording tp trappers is kinda easy, but I would like to see it, maybe even some custom ones.
You wish everyone had recording software all ready every time they switched a server to trade keys (also I sort of want it as a confirmation that I died while AFK as well, and not blown up by mentats or something weird xD)
