Suggestion

Store most recent player activity history such as items lost in a file, make admin commands for accessing player inventories and retrieving a players death location.

What lead to this suggestion: 

1. My client keeps crashing on 20w17a and when it does so at dusk it hangs for a long time. Upon re-entering the server I sometimes find I was killed during the crash and lost all my items. As my bed was broken before I died, my player.dat file did not contain the location. Luckily as it was a crash, I got kicked and on reentry my entry location was logged before being teleported to spawn.

2. I often find new players who are killed by lava or some other disaster on our server and being able to retrieve their items or take them back to where they died is painfully difficult. I did look into programming a /back function or similar but using functions to do this is likely going to cause a lot of lag.

3. If an admin dies with OP items and cannot retrieve them, it can cause serious complications for other players if stumbled upon by regular members.
